Thread: Help with arrays

How would i get the following code to print 'error' or 'true' only once after the whole array comparison in task 2 instead of printing after comparing each section of the array?

Code:

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


int main() {


char name_array[10][15];
const char * name[15];
int i;


    task1:
        for(i=0;i<10;i++){
            printf("\nEnter your name:\n");
            scanf("%s", name_array[i]);
        }




    task2:
        system("cls");
        printf("Enter your name:   ");
        scanf("%s", name);


        for(i=0;i<10;i++){


            if (strcmp(name_array[i], name)!=0){
                printf("error\n");
            } else if (strcmp(name_array[i], name)==0){
                printf("true\n");
            }
        }
}

If you want to keep processing the array once an error is found in the loop then you could add a flag and set it to 0 within the loop if there is an error (initialise it to 1 before entering the loop) and then after the loop print error or true based upon the value of the flag. E.g.

Code:

int success = 1;
for (i = 0; i < 10; i++) {
    /* ... */

    if (strcmp(name_array[i], name) != 0) {
        success = 0;
    
    /* ... */
}

if (success != 1) {
    /* ... */
} else {
    /* ... */

If you don't necessarily want to keep processing the loop once an error is found then you can use the break keyword to terminate the loop early and either use it combined with the flag strategy above, or check the value of i after the loop is terminated (if i != 10 then the loop terminated early)

thanks bro, that worked but it has a flaw. The value of 'success' is dependent on the last element of the array so even if one of the element ofthe array compared was true and the last element is false then it would still print 'error'

Yes, of course it does.

Maybe paste your latest code?
