Requirements: Use "," to separate expressions, and ";" to end a line.
In addition, 1*1=1; this formula is the first line of the program, and there is no blank line in front of it.
The text version is as follows:
Input format:
without
Output format:
1*1=1;
2*1=2,2*2=4;
3*1=3,3*2=6,3*3=9;
4*1=4,4*2=8,4*3=12,4*4=16;
5*1=5,5*2=10,5*3=15,5*4=20,5*5=25;
6*1=6,6*2=12,6*3=18,6*4=24,6*5=30,6*6=36;
7*1=7,7*2=14,7*3=21,7*4=28,7*5=35,7*6=42,7*7=49;
8*1=8,8*2=16,8*3=24,8*4=32,8*5=40,8*6=48,8*7=56,8*8=64;
9*1=9,9*2=18,9*3=27,9*4=36,9*5=45,9*6=54,9*7=63,9*8=72,9*9=81;
coding:
#include<stdio.h> intmain() { int i,j; for(i=1;i<10;i++) { for(j=1;j<=i;j++) { printf("%d*%d=%d",i,j,i*j); if(j<i) { printf(","); }else{ printf(";"); } } printf("\n"); } }
