    scanf dont work inside in a while

    Hello everybody, I dont know why, but when I put "scanf" inside of a "while, it doesnt work...

    My code is:
    Code:
    #include <stdio.h>
    
    main () {
    
        int numero[5];
        int contador = 0;
    
        while (contador < 5){
                contador++;
                printf("Enter with a value");
                scanf("%d",numero[contador]);
    
    
        }
    }
    Thank u!

    This has nothing to do with while, and everything to do with a broken scanf statement. In other words, this line
    Code:
    scanf("%d", numero[contador]);
    won't work even if you get rid of the while.

    Scanf needs to know the location of where to put the answer.

    Define "doesn't work".

    1. You shouldn't be incrementing contador until the bottom of the loop. Otherwise...
    2. Arrays start at 0, your first access point would be 1, if...
    3. You need the address of the element, not the value. Use &:
    Code:
    scanf("%d", &numero[contador]);

    Hope is the first step on the road to disappointment.
