C language is how nested WHILE loop
Users questions: #include stdio.h voidmain(){intx=1,y=1;while(x =9){y=1;while(y =x){printf( %d*%d=%d*t ,x,y,x*y);y++; ) Printf ("* n"); x ++;}} This is a multiplication table of the program, how the cycle of the cycle ah, is not the first loop printf ("% d *% d =% d * t", x, y, x * y); y + +; that a circle inside another circle outside the 777 777 First let me comment on the while statement to: while (x = 9) (y = 1; ** first call to the initial value of y 1 ** while (y = x) ** the cycle ** (printf ("% d *% d =% d * t ", x, y, x * y); * * Output x, y, x * y ** y ++;** y = 1 after call completion from the rate of increase is 2, and then returned while statement) in the main function, while statement while (x = 9) (y = 1; while (y = x) (printf ("% d *% d =% d * t ", x, y, x * y); y + +;) can be used for statement to achieve: for (y = 1; y = 9; y + +) printf ("% d *% d =% d * t ", x , y, x * y); or you can use the for statement to explain that while statements
