CO4 Assignment 5th Question solution

Define a structure named census with the following three members:

A character array city[] to store names

A long integer to store population of the city

A float member to store the literacy level.
Write a program to read details of 5 cities randomly and sort the list based on literacy level.

#include <stdio.h>

struct census

{

          char city[50];

          long int population;

          float li;

};

main()

{

          struct census temp,c[5];

          int i,p,j;

          for(i=0;i<5;i++)

          {

                    printf("\nenter city name, population and literacy level");

                    scanf("%s%ld%f",&c[i].city,&c[i].population,&c[i].li);    

          }

          for(p=0;p<4;p++)

          {

                    for(j=0;j<5-p-1;j++)

                    {

                              if(c[j].li >c[j+1].li)

                              {

                                        temp=c[j];

                                        c[j]=c[j+1];

                                        c[j+1]=temp;

                              }

                    }

          }

          printf("\nsorted order are\n");

          for(i=0;i<5;i++)

          {

                    printf("%s\t%ld\t%f\n",c[i].city,c[i].population,c[i].li);     

          }

}
