Please Help with sorting?

Hello friends, here is the entire program. My only problem is that the call function to sort(); will not work. What am I missing in this call function sort(names,size); ?

Please help.

Thank you.



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

#define MAX 4

void sort(char array[], int);

main()
{
int i, size=MAX;
char names[MAX][20];

printf("\t\t-----Enter 10 peoples names-----\n\n");

for(i=0; i<MAX; i++)
scanf("%s", names[i]);

printf("\t\t-----Names entered were as follows-----\n\n");
for(i=0; i<MAX; i++)
printf("%s\n", names[i]);

sort(names,size);

printf("\t\t-----Names sorted look as follows-----\n\n");
for(i=0; i<MAX; i++)
printf("%s\n", names[i]);

return 0;
}


void sort(char * array[], int size)
{
char* temp;
int i, j;

for (i = 0; i < size; ++i)
for (j = 0; j < size; ++j)
if (strcmp(array [i], array[j]) < 0)
{
temp = array[i];
array[i] = array[j];
array[j] = temp;
}
}

Well this doesn't match definition and use

Try
void sort(char array[MAX][20], int);

And in your sort function, you have
char* temp;

But this isn't the case is it - you dont have a pointer, you have an array

Which means you need to strcpy each array row to save/restore it.


Here

Code:

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

#define MAX 4

void sort( char array[MAX][20], int size);

int main() {
    int i, size=MAX;
    char names[MAX][20];

    printf("\t\t-----Enter 10 peoples names-----\n\n");

    for(i=0; i<MAX; i++)
        scanf("%s", names[i]);

    printf("\t\t-----Names entered were as follows-----\n\n");
    for(i=0; i<MAX; i++)
        printf("%s\n", names[i]);

    sort(names,size);

    printf("\t\t-----Names sorted look as follows-----\n\n");
    for(i=0; i<MAX; i++)
        printf("%s\n", names[i]);

    return 0;
}


void sort ( char array[MAX][20], int size)
{
    char temp[20];
    int i, j;

    for (i = 0; i < size; ++i)
        for (j = 0; j < size; ++j)
            if (strcmp(array[i], array[j]) < 0)
            {
                strcpy(temp,array[i]);
                strcpy(array[i],array[j]);
                strcpy(array[j],temp);
            }
}
