Question

In C language,

I have an array[3][2];

int i = 0, j = 0;
for (i = 0; i < 3; i++) {
    for (j = 0; j < 2; j++) {
        printf("%d", array[i][j]);
    }
}

When I use gcc to compile .c file, the error shows:

format ‘%d’ expects argument of type ‘int’, but argument 2 has type ‘int *’

How to print an array using C?

Answer 1

The error message seems pretty straight forward. It’s telling you that array[i][j] is of type int*, while the printf() “%d” formatter is expecting an argument of type int.

I’m not sure what you expect to happen here. You haven’t shown us how you declare array. But, if it’s supposed to be a two-dimensional array of int, then you declared it wrong.
