用C语言扫描字符数组

Question

I want to scan a character array as input as shown below and I also want to get the number of rows from the user (it's a square matrix).

OOX
OXO
OOX

but when I scan it using the program below, it only scans two rows.

#include <stdio.h>

int main()
{
    int size,i,j;
    printf("Enter size");
    scanf("%d",&size);

    int a[size][size];

    for(i=0;i<size;i++)
        for(j=0;j<size;j++)
            scanf("%c",&a[i][j]);

}

The output which I'm getting is:

Enter size3
OOX
OXO

then it's not asking for the last row.

Answer 1

Remember that the whitespace is not skipped here..

this would fix it, it would also consume the whitespace:

scanf(" %c",&a[i][j]);

Answer 2

Sorry, I don't have enough reputation to comment. In addition to Yohannes' answer, consider what kind of input you are expecting. You use an integer array to store values, but you tell scanf to expect characters with the "%c" . Maybe use character array or take integers as input and get rid of type mismatch warning from the compiler.

scanf("%d",&a[i][j]); to read integers
