정올 163 : 배열2-형성평가4

My Solution

#include<stdio.h>
int main (void){
    int arr[4][3]={{3, 5, 9}, {2, 11, 5}, {8, 30, 10}, {22, 5, 1}};
    int i,j,sum=0;
    for(i=0;i<4;i++){
        for(j=0;j<3;j++){
            printf("%d ",arr[i][j]);
            sum += arr[i][j];
        }
        printf("\n");
    }
    printf("%d",sum);
    return 0;
}
