Example: strchr() function in C

In this example, we have a string and we are searching a character ‘u’ in the string using strchr() function. When we displayed the string value of the returned pointer of the function, it displayed the string starting from the character ‘u’, this is because the pointer returned by the function points to the character ‘u’ in the string.

#include <stdio.h>
#include <string.h>
int main () {
   const char str[] = "This is just a String"; 
   const char ch = 'u'; 
   char *p;
   p = strchr(str, ch);
   printf("String starting from %c is: %s", ch, p);
   return 0;
}

Output:

String starting from u is: ust a String
