    Exactly what are you searching for?

    Search in a single string is dead simple... Look up strstr() ... it finds a string inside a string and returns a pointer.

    So ok... if someone enters "I want to eat an apple after my lunch"...

    Code:
    char entry[500];  // I want to eat an apple after my lunch
    char find[20];    // apple
    
    if (strstr(entry,find))
      printf("YA freaking hoo, it worked!");

    No... I'm showing you how to use strstr() a part of the standard C library... look it up!

    If all you're looking for is a conformation it's there, yes my minimal code sample will help you. If you need to do something else with it it here are other functions in the string library that will help you ... Look it up in your C language documentation.

    How you write your final code is up to you... but your search will only find a single character and thus isn't string matching.
