You can use "hash-string.h" library that converts strings into hash code integer. Create a header file and paste this code: http://www.opensource.apple.com/source/gcc/gcc-5484/intl/hash-string.h

#include 
#include 
#include "hash-string.h"

int main(){

  char name[20];

  printf("Enter a name: ");
  scanf("%s",name);

  unsigned long nameInt = hash_string(name);

  switch(nameInt){
    case 7458046 /* "kevin" */: { printf("Hello %s", name); break; }
    default: { printf("You are not kevin"); }
  }

  printf("\n");
  return 0;
}
