Algorithm (1)

Wednesday, September 30, 2009

Now, I'll try to show how to print number, with input from keyboard, and yield something like this:

Please enter number between 1-20: 10
1
1 2
1 2 3
1 2 3 4
1 2 3 4 5
1 2 3 4 5 6
1 2 3 4 5 6 7
1 2 3 4 5 6 7 8
1 2 3 4 5 6 7 8 9
1 2 3 4 5 6 7 8 9 10

We can write the algorithm in C, like this:

#include<stdio.h>

int main(void){

    int A, B, Input;

    printf("Please enter number between 1-20: ");
    scanf("%d", &Input);
    for (A = 1; A <= Input; A = A + 1){
        for (B = 1; B <= A; B = B +1){
            printf("%d ", B);
        }
        printf("\n");
    }
    return 0;
    getchar();
}
