In this tutorial, we are going to write a C Program to draw a histogram in C Programming with practical program code and step-by-step full complete explanation.

C Program to draw a histogram.

 
#include<stdio.h>
#include<conio.h>
#define N 5

void main()
{
    int value[N];
    int i,j,n,x;

    for(n=0;n<N;++n)
    {
        printf("Enter employees in group- %d",n+1);
        scanf("%d", &x);

        value[n]=x;

        printf("%dn",value[n]);
    }

    printf("n");
    printf("|n");
    for(n=0;n<N;++n)
    {
        for(i=1;i<=3;i++)
        {
            if(i==2)
                printf("Group- %d |",n+1);
            else
                printf("         |");

            for(j=1;j<=value[n];++j)
                printf("*");
            if(i==2)
                printf("(%d)n",value[n]);
            else
                printf("n");
        }
        printf("         |n");
    }
}

Output

 
Enter employees in Group - 1: 12
12
Enter employees in Group - 2: 23
23
Enter employees in Group - 3: 35
35
Enter employees in Group - 4: 20
20
Enter employees in Group - 5: 11
11
