c - 如何将输出 0/1 行更改为诸如作业/考试之类的名称

Question

我想知道如何将 sum 和 avg 的输出从 0 和 1 行更改为分配和检查。我已经完成了编码，但不知道如何仅为此输出更改代码，请帮助。下面是我的代码。

for (i = 0; i < 2; ++i)
{
    for (j = 0; j < 2; ++j)
    {
        sum = sum + arr[i][j] ;

        avg = sum/2;

    }




    printf("Total of the %d row Marks is = %.2f\n\n",i, sum);
    printf("Average of the %d row Marks is = %.2f\n\n",i, avg);;

    sum = 0;
    avg = 0;

期待以下结果

Total of the Assignment Marks is = 11.00

Average of the Examination Marks is = 5.50

Total of the Assignment Marks is = 15.00

Average of the Examination Marks is = 7.50

但我得到了这个：

Total of the 0 row Marks is = 11.00

Average of the 0 row Marks is = 5.50

Total of the 1 row Marks is = 15.00

Average of the 1 row Marks is = 7.50

使用三元运算符

例如

printf("Total of the %s row Marks is = %.2f\n\n", (i == 0? "Assignment Marks" : "Examination Marks"), sum);
