Please output half zhang Yang multiplication tables, that is, the lower triangular half zhang,
1 x 1=1
1=2 x 2 x 2=4
3 * 1=3 3 * 2=6 3 x3=9
...
9 * 1=9 September 18 9 x 3 x 2==27... 9 * 9=81
Input format:
There is no
The output format:
The result value according to the format of the output below, each method of 2, other numerical accounts for only 1, separated by a space between each pair of, the last also have space, namely the end of each row has a space, such as 1 * 1=1 followed by a space and then press enter to the second line,
1 x 1=1
1=2 x 2 x 2=4
3 * 1=3 3 * 2=6 3 x3=9
...
9 * 1=9 September 18 9 x 3 x 2==27... 9 * 9=81
Input the sample:
There is no
The output sample:
1 x 1=1
1=2 x 2 x 2=4
3 * 1=3 3 * 2=6 3 x3=9
...
9 * 1=9 September 18 9 x 3 x 2==27... 9 * 9=81

My code

#include
using namespace std;

Int main () {
int i, j;
for (i=1; i <=9; I++) {
For (j=1; J & lt;=I; J++) {
Cout & lt; }
Cout & lt;
}

return 0;
}

Why the PTA show the answer wrong, multiply the result value of two is what mean??
