정올 164 : 배열2-형성평가5

My Solution

#include<stdio.h>
int main(void){
    int arr[4][4] = {0,};
    int input, sum=0, i, j;
    
    for(i=0;i<4;i++){
        printf("%dclass? ", i+1);
        for(j=0;j<3;j++){
            scanf("%d", &arr[i][j]);
            arr[i][3] =arr[i][3] + arr[i][j];
        }
    }
    
    for(i=0;i<4;i++){
        printf("%dclass : %d\n", i+1, arr[i][3]);
    }
    
    return 0;
}
