c - 如何计算乘法表的总和

Question

我已经生成了表格，想要找到表格的总和。

代码如下:

#include <stdio.h>

int main()
{
    int no, i, mult, sum;

    printf("Enter the number you wish to multiply: \n");
    scanf("%d", &no);

    printf("Enter how many times you want to multiply the number: \n");
    scanf("%d", &mult);

    printf("Multiplication is as follows: \n");

    for( i = 1; i <= mult; i++ )
    {
        printf("%d X %d = %d\n", no, i, i * no);
    }
}

如何获取整个表格的总和？

Answer 1

在开始时初始化 sum = 0，然后每次打印一个值时将其添加到总和中。

#include <stdio.h>
#include <stdlib.h>
#include<conio.h>

int main()
{
  int no,i,mult,sum=0;

  printf("Enter the number you wish to multiply: \n");
  scanf("%d", &no);

  printf("Enter how many times you want to multiply the number: \n");
  scanf("%d", &mult);

  printf("Multiplication is as follows: \n");

  for(i = 1; i <= mult; i++)
  {
      printf("%d X %d = %d\n", no,i,i*no);
      sum = sum + i*no
  }
  printf("sum = %d", sum);
}
