a string. [25 Marks]
#include <stdio.h>
#include <string.h>
 // Driver code
int main()
{ char str[50]= "geeksforgeeks";
 char c ;
 int res = 0;
 printf("\n enter character ");
 scanf("%c",&c);
 for (int i=0;i<strlen(str);i++)
 // checking character in string
 if (str[i] == c)
 res++;
 printf("occurence of %c=%d",c,res++);
 return 0;
}
