输出9*9乘法表（包括输出格式）
精选 原创#每日美图分享#
#include<stdio.h>
int main()
{
int num1;
int i = 0;
int sum = 0;
int arr[] = { 1,2,3,4,5,6,7,8,9 };
for (num1 = 1; num1 < 10; num1++)
{
i = num1-1;
for (; i <9; i++)
{
sum = num1 * arr[i];
printf("%d*%d=%d ",num1,arr[i],sum);
}
}
return 0;
}
int main()
{
int num1;
int i = 0;
int sum = 0;
int arr[] = { 1,2,3,4,5,6,7,8,9 };
for (num1 = 1; num1 < 10; num1++)
{
i = num1-1;
for (; i <9; i++)
{
sum = num1 * arr[i];
printf("%d*%d=%d ",num1,arr[i],sum);
}
}
return 0;
}
可以看到这样只是输出了结果，并没有打印出9*9乘法表的格式。
进一步修改思路：打印1*1的结果后换行，再打印1*2，2*2的结果后换行，以此类推。
#include<stdio.h>
int main()
{
int num1 = 1; //有结构的乘法表
int arr[] = { 1,2,3,4,5,6,7,8,9 };
int i = 0;
int sum = 0;
for (num1 = 1; num1 < 10; num1++)
{
for (i = 0; i < 9; i++)
{
if (arr[i] <= num1)
{
sum = num1 * arr[i];
printf("%d*%d=%d ", num1, arr[i], sum);
}
}
printf("\n"); //换行
}
return 0;
}
int main()
{
int num1 = 1; //有结构的乘法表
int arr[] = { 1,2,3,4,5,6,7,8,9 };
int i = 0;
int sum = 0;
for (num1 = 1; num1 < 10; num1++)
{
for (i = 0; i < 9; i++)
{
if (arr[i] <= num1)
{
sum = num1 * arr[i];
printf("%d*%d=%d ", num1, arr[i], sum);
}
}
printf("\n"); //换行
}
return 0;
}
虽然有了基本格式，但还是没对齐。
#include<stdio.h>
int main()
{
int num1 = 1;
int arr[] = { 1,2,3,4,5,6,7,8,9 };
int i = 0;
int sum = 0;
for (num1 = 1; num1 < 10; num1++)
{
for (i = 0; i < 9; i++)
{
if (arr[i] <= num1)
{
sum = num1 * arr[i];
printf("%d*%d=%-2d ", num1, arr[i], sum);
}
}
printf("\n");
}
return 0;
}
int main()
{
int num1 = 1;
int arr[] = { 1,2,3,4,5,6,7,8,9 };
int i = 0;
int sum = 0;
for (num1 = 1; num1 < 10; num1++)
{
for (i = 0; i < 9; i++)
{
if (arr[i] <= num1)
{
sum = num1 * arr[i];
printf("%d*%d=%-2d ", num1, arr[i], sum);
}
}
printf("\n");
}
return 0;
}
现在就对齐了，完美收官！
