    comparing strings: case INsensitive

    I'm trying to write a program that takes in a list of names and ages, then searches for a certain first name and last name. However, in the problem prompt, it requires that the comparison between the name and search value to be case insensitive. I've tried stricmp() but I don't think the compiler I'm using uses it (GCC). Here's my code for my search() function so far.

    Code:
    int search( char names[20][20], int ages[20], char value[20], int *totAges )
    {
      char tempArr[20];
      int rCtr = 0;
      int cCtr = 0;
      int ctr = 0;
      int ageCtr = 0;
    
      for( rCtr = 0; rCtr < 20; rCtr++ ) {
        strcpy( tempArr, names[rCtr] );
        if( !strcmp( tempArr, value ) ) {
          ctr++;
          printf( "%d\n", ages[rCtr] );
          ageCtr += ages[rCtr];
        }
      }
      *totAges = ageCtr;
    
      return ctr;
    }
    Any help would be greatly appreciated. Thanks!

    No problem. Just be aware that strcasecmp() is not portable. So outside of GCC your code may not even work. But its all good, you didn't seem like that was an issue.

    And many other compilers have "stricmp" that does the same thing.

    And it's not terribly hard to do the same thing if you need to.

    How comes there is stricmp() in MinGW?
    Vanity of vanities, saith the Preacher, vanity of vanities; all is vanity.
    What profit hath a man of all his labour which he taketh under the sun?
    All the rivers run into the sea; yet the sea is not full; unto the place from whence the rivers come, thither they return again.
    For in much wisdom is much grief: and he that increaseth knowledge increaseth sorrow.

    MinGW uses the Microsoft CRT (that comes with VC 6.0, msvcrt.dll), and exposes all of its functionality.
