C Program to sort array of Structure in C Programming

Problem Statement : C Program to sort array of Structure in C Programming

Write a C program to accept records of the different states using array of structures. The structure should contain char state, population, literacy rate, and income. Display the state whose literacy rate is highest and whose income is highest.

Problem to display the highest literate rate and the highest income of a state using array of structures

#include<stdio.h>
#include<conio.h>
#define M 50
struct state
{
    char name[50];
    long int populat;
    float lit_rate;
    float income;
}st[M];     /* array of structure */
void main()
{
int i,n,ml,mi,maxlrate, maxinc;
float rate;
ml=mi=-1;
maxlrate=maxinc=0;
clrscr();
printf("\nEnter how many states:");
scanf("%d",&n);
for(i=0;i<n;i++)
  {
    printf("\nEnter state %d details :",i);
    printf("\n\nEnter state name : ");
    scanf("%s",&st[i].name);
    printf("\nEnter total population : ");
    scanf("%ld",&st[i].populat);
    printf("\nEnter total literary rate : ");
    scanf("%f",&rate);
    st[i].lit_rate=rate;
    printf("\nEnter total income : ");
    scanf("%f",&st[i].income);
  }
for(i=0;i<n;i++)
{
    if(st[i].lit_rate>=maxlrate)
        {
        maxlrate=st[i].lit_rate;
        ml++;
        }
    if(st[i].income>maxinc)
        {
        maxinc=st[i].income;
        mi++;
        }
}
printf("\nThe state whose literary rate is the highest : %s",st[ml].name);
printf("\nThe state whose income is the highest : %s",st[mi].name);
getch();
}

Output :

Enter how many states:3
Enter state 0 details :
Enter state name : Maharashtra
Enter total population : 1000
Enter total literary rate : 90
Enter total income : 10000
Enter state 1 details :
Enter state name : Goa
Enter total population : 300
Enter total literary rate : 94
Enter total income : 5000
Enter state 2 details :
Enter state name : Gujrat
Enter total population : 900
Enter total literary rate : 78
Enter total income : 7000
The state whose literary rate is the highest : Goa
The state whose income is the highest : Maharashtra
