Function that receives a string as a parameter and returns the length of that string
I try to create a function to return the length of the string but somehow it doesn't work! ' could you please help me check it? Here is the code : #include <stdio.h> int my_strlen(char *s){ int length =0; while(*s !='\0'){ s++; length ++; } return x; } int main() { printf("------------------------\n"); my_strlen("abcd") ; }

As Angelo said, x is not declared, but you also are not printing the value returned by my_strlen.
And if you want you can use a more concise for loop instead of the while.

You haven't defined x
You probably meant:
return length;
0
#include <stdio.h>
#include <string.h>
int my_strlen(char *s){
int length = 0;
while(*s++)
length++;
return length;
}
int main()
{
printf("%d", my_strlen("abcd"));
return 0;
}
// or
int my_strlen(char *s){
int i=0;
for(; *s++; i++);
return i;
