The code is like 5 lines, you get what I'm going for here. I'm pretty sure I did the scanf correctly, I don't know why the if won't work, I tried " and ' and & but its not working
Code:
#include <stdio.h>
#include <stdlib.h>
int main() {
char name[20];
printf("Enter your name: \n");
scanf(" %s", name);
if (name == 'Eric') {
printf("Your name is Eric");
}
return 0;
}
In C, you need to explicitly invoke a comparison function to get the logical comparison result for any type other than a primitive number type (ex.
int,
float). In the case of strings, the function you want is
strcmp, defined in header
<string.h>.
And why you need strcmp: the type of name in the comparison is char*, and "Eric" is also of type char*. You're checking whether the pointers point to the same thing, which will always be false in this case.
Yes as mentioned strcmp is the function that you are after:
int strcmp(const char *str1, const char *str2)
strcmp returns 0 when the strings are equal, a negative integer when str1 is less than str2, or a positive integer if str1 is greater than str2, according to the lexicographical order.
So it would be:
if(strcmp(name, "Eric") == 0) {
printf("Your name is Eric");
}
