(Use function) Write a function-oriented program that scans a number n and then output the sum of the powers from 1 to n. Thus, if the input is 3, the output should be 14. Because of this computation: 12+22+32= 1+4+9 =14

Sample input/output dialogue:
Enter number: 3
The result is: 1 + 4 + 9 = 14
modify my program:
#include <stdio.h>
#include <conio.h>
#include <stdlib.h>
#include <string.h>
int exponential(int x);
void main(){
int value;
system("cls");
printf("Enter number: "); scanf("%d",&value);
printf("%d",exponential(value));
}
int exponential(int a)
{
int i,total=0;
for(i=1;i<=a;i++)
{
if(i!=a)
{
printf("%d + ",i*i);
}
else if (i==a)
{
printf("%d = ",i*i);
}
total += i*i;
}
getch();
return total;
}
