编程输出九九乘法表倒三角(编写程序九九乘法表倒三角)
如何用C语言写出一个九九乘法表,输出格式是倒三角形状,就是上面多下面少?
#include stdio.h
void main()
{
int i;
int j;
for (i = 1; i = 9; i++)
{
for (j = 1; j = i; j++)
{
printf("%-4d*%-4d=%-4d\n", j, i, j * i);
}
}
}
就这样吧,上三角的没见过,可以考虑换行,如果需要,再联系。
c语言输出九九乘法表(选择1为正三角,选择2为倒三角)
#include?stdio.h
int?main()
{
????int?n,i,j;
????scanf("%d",n);
????if(n?==?1)
????{
????????for(i?=?1;?i=9;?i?++)
????????{
????????????for(j?=?1;?j?=?i;?j?++)
????????????{
????????????????printf("%-2d?*?%-2d?=?%-4d",?i,?j,?i*j);
????????????}
????????????printf("\n");
????????}
????}
????else?if(n?==?2)
????{????
????????for(i?=?1;?i=9;?i?++)
????????{
????????????for(j?=?1;?j?=?10-i;?j?++)
????????????{
????????????????printf("%-2d?*?%-2d?=?%-4d",?i,?j,?i*j);
????????????}
????????????printf("\n");
????????}
????}
}
c语言编写九九乘法表 要成倒三角
#include stdio.h
int main(void)
{
int i;
int l;
int sum;
for (i = 1; i = 9; i ++)
{
for (l = 1; l = i; l ++)
{
sum = i * l;
printf("%d*%d=%-3d",l,i,sum);
}
printf("\n");
}
return 0;
}
