strchr
Description:

Prototype:
Arguments:
Return Value:
Remarks:
Example:
Locates the first occurrence of a specified character in a string.
<string.h>
char *strchr(const char *s, int c);
s
c
Returns a pointer to the location of the match if successful; otherwise,
returns a null pointer.
This function searches the string s to find the first occurrence of the
character c.
#include <string.h> /* for strchr, NULL */
#include <stdio.h>
int main(void)
{
if (ptr != NULL)
if (ptr != NULL)
}
Output:
buf1 : What time is it?
m found at position 8
y not found
char buf1[50] = "What time is it?";
char ch1 = 'm', ch2 = 'y';
char *ptr;
int res;
printf("buf1 : %s\n\n", buf1);
ptr = strchr(buf1, ch1);
{
}
else
printf("\n");
ptr = strchr(buf1, ch2);
{
}
else
res = ptr - buf1 + 1;
printf("%c found at position %d\n", ch1, res);
printf("%c not found\n", ch1);
res = ptr - buf1 + 1;
printf("%c found at position %d\n", ch2, res);
printf("%c not found\n", ch2);
