C程序数组需要的输入过多

Question

I was just playing around and i created a two D array in C of 3 rows and three columns and set a nested for loops to scan the elements. Now, a three by three matrix has Nine elements but this code is taking 10 inputs(even the for loop is running only 9 times) How is it happening???

#include <stdio.h>


int main(){
int array[3][3];
int i,j;
for(i = 0; i < 3; ++i){
    for(j = 0; j < 3; ++j){
        printf("i = %d j = %d\n",i,j);
        scanf(" %d ",&array[i][j]);
        printf("i = %d j = %d\n",i,j);
    }
}

Answer 1

scanf(" %d " --> scanf("%d"

Probably , the space after %d results in scanf waiting for another input. So, remove the space and it should work fine.

Answer 2

scanf("%d ",&array[i][j]) ----> scanf("%d",&array[i][j])

这可能有助于解决它
