Description
Scans a string for the first occurrence of a given character.
strchr scans a string in the forward direction, looking for a specific character. strchr finds the first occurrence of the character c in the string s. The null-terminator is considered to be part of the string.
For example:
strchr(strs,0)
returns a pointer to the terminating null character of the string strs.
Return Value
strchr returns a pointer to the first occurrence of the character c in s; if c does not occur in s, strchr returns null.
Example
#include <string.h>
#include <stdio.h>
int main(void)
{
char string[15];
char *ptr, c = 'r';
strcpy(string, "This is a string");
ptr = strchr(string, c);
if (ptr)
printf("The character %c is at position: %d\n", c, ptr-string);
else
printf("The character was not found\n");
return 0;
}
