hey guys, i need help about this problem....
i am sorting a number of names, but if i inputted a lower case and a upper case value, it will not be equal.

1 2 3 4 5 6

example: Enter number of names; 3 Enter names: albert Albert Nel

The sorted names: Albert Nel albert

i need help.. this is my codes..

#include<stdio.h>
#include<stdlib.h>
#include<string.h>

int main()
{
    int y,x,n,j;
    char names[20][20],temp[20];
    
    puts("Enter number of students: ");
    scanf("%d",&n);
    
    j = n + 1;
    puts("Input the names");
    for(x = 0;x < j;x++)
        gets(names[x]);
    
    for(x = 0;x < j;x++)
    { 
       for(y = x + 1;y < j;y++)
       {
             if(strcmp(names[x],names[y])>0)
             {
                strcpy(temp,names[x]);
                strcpy(names[x],names[y]);
                strcpy(names[y],temp);
             }
       }
    }      
    printf("--------------------\n");
    puts("The sorted names");
    for(x = 0;x < j;x++)
        puts(names[x]);
    
    system("pause");
    return 0;
}

I don't think there's a case-insensitive version of strcmp(). You'll have to either convert all the strings to the same case before starting, or write your own version of strcmp().

[jsmith]

int strcasecmp( const char* s1, const char* s2 );

[helios]

Is that standard?

[jsmith]

The man page only says BSD 4.4 as opposed to the man page for strcmp which
lists SVID 3, POSIX, BSD 4.3, ISO 9899.

On the other hand the man page does not say anything about being non-portable.

Hmm....

jeysel, just write your own strcmp that is case-insensitive. No reason to use something non-standard for something so simple.
