C language · Multiplication table

The problem description output 99 multiplication table. The output format output format is shown in the following example. Multiplication sign is denoted by "*". The sample output below gives the first few lines of the output:
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
......

1#include <stdio.h>2 intMain () {3     intI,j,n;4      for(i=1; i<=9; i++){5          for(j=1; j<=i;j++)6printf"%d*%d=%d", i,j,i*j);7printf"\ n");8     }9}

The format is more beautiful (but the output style does not match test instructions):

1#include <stdio.h>2 intMain () {3     intI,j,n;4printf"\ n");5      for(i=1; i<=9; i++){6          for(j=1; j<=i;j++)7printf"%d*%d=%2d", i,j,i*j);8printf"\ n");9     }Ten      Oneprintf"\ n");p rintf ("\ n"); A      -      for(i=1; i<=9; i++){ -         //comment out the for loop below to output the lower left triangle the          for(n=1; n<=9-I.; n++) -printf"        "); -          for(j=1; j<=i;j++) -printf"%d*%d=%2d", i,j,i*j); +          -printf"\ n"); +     } A}
