It's working now! see below.
Thank you's for the suggestions everyone!
This project now has a github repo : https://github.com/Izder456/scarf

*A bunch of deleted stuff*

Edit : working code

I got the code working in C :

Code:

//////////////////////

// Author   : izder456


// License  : N/A


// Version  : v1.0.1


// Language : C


//////////////////////





#include <stdio.h>


#include <math.h>





int main(void) {


  int colour_length, pattern_length, pattern_width, pos, _pj_a;


  char colour1, colour2;





  printf("Enter Charater 1 : ");


  scanf(" %c",&colour1);


  printf("Enter Charater 2 : ");


  scanf(" %c",&colour2);


  printf("Enter desired Character length (Whole Number) : ");


  scanf(" %i",&colour_length);


  printf("Enter desired scarf length (Whole Number) : ");


  scanf(" %i",&pattern_length);


  printf("Enter desired scarf width (Whole Number) : ");


  scanf(" %i",&pattern_width);





  char colours[2] = {colour1, colour2};


  


  printf("\n");


  printf("Here is your scarf : \n");


  _pj_a = (pattern_width * pattern_length);


  for (pos = 0;pos<_pj_a; pos++) {


    printf("%c",colours[(pos / colour_length) % sizeof(colours)]);


    if (((pos % pattern_width) == (pattern_width - 1))) {


      printf("\n");


    }


  }


}

I got the code working in C++ :

Code:

int main(void) {

  std::cout << ("Enter Charater 1 : ");


  std::cin  >> colour1;


  std::cout << ("Enter Charater 2 : ");

  std::cin  >> pattern_width;





  char colours[2] = {


    colour1,


    colour2


  };





  std::cout << ("\n");


  std::cout << ("Here is your scarf : \n");


  _pj_a = (pattern_width * pattern_length);


  for (pos = 0; pos < _pj_a; pos++) {


    std::cout << (colours[(pos / colour_length) % sizeof(colours)]);


    if (((pos % pattern_width) == (pattern_width - 1))) {


      std::cout << ("\n");


    }


  }


  return 0;


}

I got the code working in Node.js :

Code:

const prompt = require('prompt-sync')({


  sigint: true


});





var colour_length, colours, pattern_length, pattern_width;





colours = [prompt("Enter Charater 1 : "), prompt("Enter Charater 2 : ")];


colour_length = Number.parseInt(prompt("Enter desired Character length (Whole Number) : "));


pattern_length = Number.parseInt(prompt("Enter desired scarf length (Whole Number) : "));


pattern_width = Number.parseInt(prompt("Enter desired scarf width (Whole Number) : "));





console.log();


console.log("Here is your scarf : ");


_pj_a = (pattern_width * pattern_length);


for (var pos = 0;(pos < _pj_a); pos++ ) {


  process.stdout.write(colours[(Number.parseInt((pos / colour_length)) % colours.length)]);


  if (((pos % pattern_width) === (pattern_width - 1))) {


    console.log(); // fixes stdout writing "true" at end


  }


}

I got the code working in Python 3 :

Code:

#######################


## Name     : scarf.py


## Author   : izder456


## License  : N/A

## Language : Python


#######################





colours = [input("Enter Charater 1 : "),input("Enter Charater 2 : ")]


colour_length = int(input("Enter desired Character length (Whole Number) : "))


pattern_length = int(input("Enter desired scarf length (Whole Number) : "))


pattern_width = int(input("Enter desired scarf width (Whole Number) : "))





print()


print("Here is your scarf :")


for pos in range(int(pattern_width * pattern_length)):


    print( colours[ int((pos)/colour_length) % len(colours)], end="")


    if (pos % pattern_width) == pattern_width-1:


        print("")

here's it running :

1. %s is for strings. Use %c.
2. No idea what you are doing with that colours array. You probably meant colours[2].
3. So much is so weird I can't say anything else without compiling it myself, which might happen someday.

i fixed that :

Code:

scanf("Enter Charater 1 : %c",&colour1);


scanf("Enter Charater 2 : %c",&colour2);

Done :

Code:

char colours[2] = {colour1, colour2};

It still hangs at execution with your suggestions

BTW : Here's my updated program :

Code:




#include <stdio.h>


#include <math.h>





int main(void) {


  int colour_length, pattern_length, pattern_width, pos, _pj_a;


  char colour1, colour2;


  scanf("Enter Charater 1 : %c",&colour1);


  scanf("Enter Charater 2 : %c",&colour2);


  char colours[2] = {colour1, colour2};





  scanf("Enter desired Character length (Whole Number) : %i",&colour_length);


  scanf("Enter desired scarf length (Whole Number) : %i",&pattern_length);


  scanf("Enter desired scarf width (Whole Number) : %i",&pattern_width);


  


  printf("\n");


  printf("Here is your scarf : ");


  _pj_a = (pattern_width * pattern_length);


  for (pos = 0;pos<_pj_a; pos++) {


    printf("%c",colours[(pos / colour_length) % sizeof(colours)]);


    if (((pos % pattern_width) == (pattern_width - 1))) {


      printf("\n");


    }


  }


}

EDIT : It supposed to print a text scarf using the inputs given

EDIT 2 : Here's the Node.js code running so you see what it's supposed to do. https://scarfjs.isaacmeyer.repl.run

Your program's not hanging, it's just not printing the prompt text you're using in scanf(). Actually, I don't know what scanf() is doing with the string you inputted, but it's not what you want.

Use printf() instead. Example:

Code:

printf("Enter desired Character length (Whole Number) : ")


scanf("%i",&colour_length);

Here's my updated code :

Code:

#include <stdio.h>


#include <math.h>





int main(void) {


  int colour_length, pattern_length, pattern_width, pos, _pj_a;


  char colour1, colour2;


  printf("Enter Charater 1 : ");


  scanf("%c",&colour1);


  printf("Enter Charater 2 : ");


  scanf("%c",&colour2);


  char colours[2] = {colour1, colour2};


  


  printf("Enter desired Character length (Whole Number) : ");


  scanf("%i",&colour_length);


  printf("Enter desired scarf length (Whole Number) :");


  scanf("%i",&pattern_length);


  printf("Enter desired scarf width (Whole Number) : ");


  scanf("%i",&pattern_width);





  


  printf("\n");


  printf("Here is your scarf : ");


  _pj_a = (pattern_width * pattern_length);


  for (pos = 0;pos<_pj_a; pos++) {


    printf("%c",colours[(pos / colour_length) % sizeof(colours)]);


    if (((pos % pattern_width) == (pattern_width - 1))) {


      printf("\n");


    }


  }


}

but whatever i input for the first question, it skips the next one a goes right on to the third prompt.

Any Ideas why this new problem is happening?

Edit : I tried Jacobly's suggestions with putting \n in the scanf's
here's my update code :

Code:

#include <stdio.h>


#include <math.h>





int main(void) {


  int colour_length, pattern_length, pattern_width, pos, _pj_a;


  char colour1, colour2;


  printf("Enter Charater 1 :");


  scanf("%c\n",&colour1);


  printf("Enter Charater 2 :");


  scanf("%c\n",&colour2);





  printf("Enter desired Character length (Whole Number) : ");


  scanf("%i\n",&colour_length);


  printf("Enter desired scarf length (Whole Number) :");


  scanf("%i\n",&pattern_length);


  printf("Enter desired scarf width (Whole Number) :");


  scanf("%i\n",&pattern_width);





  char colours[2] = {colour1, colour2};


  


  printf("\n");


  printf("Here is your scarf : \n");


  _pj_a = (pattern_width * pattern_length);


  for (pos = 0;pos<_pj_a; pos++) {


    printf("%c",colours[(pos / colour_length) % sizeof(colours)]);


    if (((pos % pattern_width) == (pattern_width - 1))) {


      printf("\n");


    }


  }


}

Use scanf(" %c", &value); for all uses. Note the single space.
