C program of minimum cost problem

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

C Program of the minimum cost problem.

 
#include<stdio.h>
#include<conio.h>

void main()
{
    float p, cost, p1, cost1;

    for(p=0; p<=10; p=p+0.1)
    {
        cost=40-8*p+p*p;

        if(p==0)
        {
            cost1=cost;
            continue;
        }

        if(cost>=cost1)
            break;
        cost1=cost;
        p1=p;
    }

    p=(p+p1)/2.0;
    cost=40-8*p+p*p;

    printf("MINIMUM COST = %2f AT p=%.1f", cost,p);
}

Output

 
MINIMUM COST = 24.00 AT p=4.0
