I am not sure why c=1 and b=1, c=1 were given among the main(intm) functions in the source code above. For your information, I didn't plan the source code above.
c
Although the c language is concise, the for syntax is not so neat.
In the grammatical structure of for (initial value; value up to repetition; value up to initial value)
Giving the values of a, b, and c by 1 is setting the initial value.
If for is in for, it is a two-dimensional data representation.
You can think of Gugudan as a representative.
for(int x = 2; x < 10; x++){
for(int y = 1; y < 10; y++){
printf("%d * %d = %d\n", x, y, x * y);
}
}
위의 코드는
2 * 1 = 2
2 * 2 = 4
...
9 * 1 = 9
9 * 2 = 18
...
9 * 9 = 81
It's going to be it.
Please compile and run the code above and learn how x and y values change with one-line debugging.
