Question

I need to write a function that prints to the screen. If the input is 5, then the output is:

+**
****
*******
***********
****************

This is my current code:

int recursions(int number,int condition)
{
    if(condition < 0)
    {
        printf("\n");
        return 0;
    }
    else
    {
        printf("**");
        recursions(number + 2,condition - 1);
    }
}

int main()
{
    int number;
    printf("Please give a number!\n");
    scanf("%d",&number);
    printf("+");
    recursions(number,number);
    getch();
}

#include <stdio.h>

void print(int n){
    if(n > 0){
        putchar('*');
        print(n-1);
    } else
        putchar('\n');
}

void recursions(int n,int cond){
    if(cond > 0){
        print(n*(n-1)/2 + 1);
        recursions(n+1, cond-1);
    }
}

int main(){
    int number;
    printf("Please give a number!\n");
    scanf("%d",&number);
    printf("+");
    recursions(2,number);
    getch();
}
