C Programming representing array values with stars

[Travercraig]

Right so I have this program that nearly works, the only thing that isn't working is printing out stars. What the program is supposed to do is match the amount of stars printed with each value in the array. Currently I have this code: 

#include <stdio.h>int main(){        char star = '*';		int i;		//int s;        int lottery[49] = { 23,16,18,19,26,13,22,    /*  1 ..  7 */                            20,14,22,18,21,15,17,    /*  8 .. 14 */                            24,15,18,20,13,14,20,    /* 15 .. 21 */                            18,22,20,16,19,11,20,    /* 22 .. 28 */                            16,28,22,20,15,17,17,    /* 29 .. 35 */                            21,21,19,20,14,22,25,    /* 36 .. 42 */                            19,17,26,18,20,23,12 };  /* 43 .. 49 */											for (i = 0; i < 49; i++)		{		     printf(" %2d  (%d)  |  %c\n", i+1, lottery[i], star);			 		}	    						return 0;}

The program is supposed to do this in the (picture 1 below)

But the output is currently this (picture 2 below)

well, that would be because you didn't tell it to print the star more than once. Simply add a second loop inside the first one that prints a star <lottery> times.

you need another for loop that loops lottery times and has printf(star) or whatever

I tried adding for (star = 0; star < lottery; star++) inside the first loop but that didn't work. I'm not actually sure what i'd need to write in this second for loop.

int a;for (i = 0; i < 49; i++)		{		     printf(" %2d  (%d)  |  ", i+1, lottery[i]);	             for(a = 0; a < lottery[i]; a++) printf("*");                     printf("\n");		}

You have an initial for loop that iterates through the array. Now you need a second one to iterate how many stars.i+1, lottery[i]

Try:

//loops through the array.for (i = 0; i < 49; i++){       printf("%2d (%d) |", i+1, lottery[i]);        //loops to print stars.       for(int j = 0; j < lottery[i]; j++)       {                 printf(" *");       }              //Changes line between star printing       printf("\n"); //Sorry, I forgot this. Good work Sauron for beating me to the point.            }

Well the program works, but now it's just a case of fomatting it correctly. It does this now which i'm trying to figure out:

#include <stdio.h>int main(){        //char star = '*';		int i;		int s;        int lottery[49] = { 23,16,18,19,26,13,22,    /*  1 ..  7 */                            20,14,22,18,21,15,17,    /*  8 .. 14 */                            24,15,18,20,13,14,20,    /* 15 .. 21 */                            18,22,20,16,19,11,20,    /* 22 .. 28 */                            16,28,22,20,15,17,17,    /* 29 .. 35 */                            21,21,19,20,14,22,25,    /* 36 .. 42 */                            19,17,26,18,20,23,12 };  /* 43 .. 49 */											for (i = 0; i < 49; i++)		{		     printf(" %2d  (%d)  |  ", i+1, lottery[i]);			 			 for (s = 0; s < lottery[i]; s++)			{				printf("*");										printf("\n");			}			 		}	    						return 0;}

well of course, you print a newline every time you print a star. Put it outside the second loop like I did.

Move the "printf("\n");" outside of the for loop that it's nested in. Just put the brace in the line above it and remove the one directly below it and fix spacing.

Oh yeah I didn't spot that, sorry. Thanks for your help.

Thanks! I do what I can but the guys who frequent the forums are a lot quicker than me!
