Python语言:
for i in range(1,10):
for j in range(1,i+1):
print("%d*%d=%2d"%(j,i,j*i),end=' ')
print("")
Java语言:
public class ForDemo1
{
public static void main(String[] args)
{
for(int i=1;i<=9;i++)
{
for(int j=1;j<=i;j++)
{
System.out.print(j+"*"+i+"="+j*i+"\t");
}
System.out.println();
}
}
}
Golang语言:
package main
import "fmt"
func main() {
for y := 1; y <= 9; y++ {
for x := 1; x <= y; x++ {
fmt.Printf("%d*%d=%d ", x, y, x*y)
}
fmt.Println()
}
}
PHP语言:
<?php
for($j=1; $j<=9; $j++) {
for($i=1; $i<=$j; $i++) {
echo "{$i}x{$j}=".($i*$j)." ";
}
echo "<br />";
}
执行以上代码输出结果为:
1x1=1
1x2=2 2x2=4
1x3=3 2x3=6 3x3=9
1x4=4 2x4=8 3x4=12 4x4=16
