Complete C Program to Convert Rupees into Paisa

Below is the complete code:

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

int main()
{
    float rs;  // Define variable for rupees
    int ps;    // Define variable for paisa
    clrscr();

    printf("\n\n Kindly enter the value in Rupees to convert into Paisa: ");
    scanf("%f", &rs);

    ps = rs * 100;  // Conversion logic

    printf("\n The value in Paisa is: %d", ps);

    getch();
    return 0;
}

Explanation of the Code

1. Variable Declaration:

   • float rs: Used to store the amount in Rupees.
   • int ps: Used to store the amount in Paisa after conversion.

2. Input Statement:

   • The scanf function is used to take the user input for the value of Rupees.

3. Conversion Logic:

   • The value in Rupees is multiplied by 100 to convert it into Paisa.

4. Output Statement:

   • The printf function displays the result in Paisa.

5. Program Flow:

   • The program waits for the user to input a value in Rupees.
   • It performs the conversion and displays the result.

Sample Output

Input:

Kindly enter the value in Rupees to convert into Paisa: 12.50

Output:

The value in Paisa is: 1250
