Question

I need to write a program in pure C. I wish to fill an array with user inputted floats and my function at the moment looks like this:

int fillWithCustom(float *array, int size) {
    float customNumber;
    for (i = 0; i < size; i++)
        for (j = 0; j < size; j++) {            
            printf("\n Enter [%d][%d] element: ", i , j);
            scanf("%f", &customNumber);
            *(array+i*size+j) = customNumber;
        }
    return 1;
}

But when I enter wrong number or char, iteration continues to an end…(Ex. I enter “a” as first element, then both for cycles iterate without scanf’s and array is filled with 0‘s.

Don;t use scanf() for user input. It was written to be used with formatted data. User input and formatted data are as different as night from day.

Use fgets() and strtod().
