C program to read a value and print its corresponding percentage from 1% to 100% using recursion

This code presents a usage of Recursive functions in C.

In this example the user input is broken into its corresponding percentage value for 1%age to 100% using recursion.

#include<stdio.h>

//function declaration
int RecursvFcnTogetPrcntge();

float Var;
unsigned int count=1;
float Prcntge;

int main()
{

    printf("\nEnter a value to split in percentage: ");
    scanf("%f",&Var);

    Var=Var/100;
    RecursvFcnTogetPrcntge();
    printf("\n");
    
    return 0;
}

int RecursvFcnTogetPrcntge()
{

    if(count==101)
    {
        return 1;
    }

    Prcntge=Var*count;
    printf("\n%3d Percent = %.02f",count, Prcntge);
    count++;
    RecursvFcnTogetPrcntge();
    return 0;
}

Output

Enter a value to split in percentage: 1340   
 
  1 Percent = 13.40  
  2 Percent = 26.80  
  3 Percent = 40.20  
  4 Percent = 53.60  
  5 Percent = 67.00  
  6 Percent = 80.40  
  7 Percent = 93.80  
  8 Percent = 107.20 
  9 Percent = 120.60 
 10 Percent = 134.00 
 11 Percent = 147.40 
 12 Percent = 160.80 
 13 Percent = 174.20 
 14 Percent = 187.60 
 15 Percent = 201.00 
 16 Percent = 214.40 
 17 Percent = 227.80 
 18 Percent = 241.20 
 19 Percent = 254.60 
 20 Percent = 268.00 
 21 Percent = 281.40 
 22 Percent = 294.80 
 23 Percent = 308.20 
 24 Percent = 321.60 
 25 Percent = 335.00 
 26 Percent = 348.40 
 27 Percent = 361.80 
 28 Percent = 375.20
