Question

In a C language program CODE BLOCKS !!!!!!!!

Program that stores the number of votes obtained by 3 amounts in five different zones. Is required:
+ Request the total of votes by zone of each candidate, the values must be entered on the keyboard and validate that it does not accept negative numbers
+ Menu that requests the operation to be performed, in case of entering an invalid data send an error message and request the operation again
+ Option to perform another calculation

Note: The code must perform the calculations throughout the array, operations are not accepted assuming different values to the elements of the array

What will be told in the program:
* The area that obtained the most votes
* Total votes for each candidate
* The candidate with the fewest votes
* The number of votes obtained by zones
*Option menu
* Validate Negative data
* Request if you want to make another calculation

Answer 1

code:

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

// Declaring a function which takes input
void read_input(int a[],int x);

// Declaration of arrays which stores votes
int p1[5],p2[5],p3[5],total[5];
void main()

   //Declaration of necessary variables
   int i,choose,cal,p1_total=0,p2_total=0,p3_total=0;
  

   // calling read_input function which reads input from the user
   read_input(p1,1);
   read_input(p2,2);
   read_input(p3,3);
      
   // Calculating total votes in each Zone
   for(i=0;i<5;i++)

       {
           for(i=0;i<5;i++)

       scanf("%d",&cal);
   }while(cal==1);
