   i) If a is not equal to b, execute the following steps:

   Print "A is not equal to B".

   Use nested if-else statements to determine which integer is larger:

     If `a` is greater than `b`, print "A is larger than B".
   
     If `b` is greater than `a`, print "B is larger than A".
   

   ii) If a is equal to b, print "A is equal to B".

PROGRAM:

#include<stdio.h>
int main()
{
    int a,b;

EXPERIMENT-5-RATE OF INTEREST CALCULATOR

AIM:

To create a program that calculates the rate of interest based on the principal amount, rate, and simple interest provided by the user.

ALGORITHM:

1. Begin the program.
2. Declare variables p (principal), r (rate), si (simple interest), and y (rate of interest in percentage) of type float.
3. Prompt the user to input the principal amount, rate, and simple interest.
4. Read the input values for p, r, and si using scanf() function.
5. Calculate the rate of interest (y) using the formula: [ y = \frac{si \times 100}{r \times p} ]
6. Print the rate of interest (y) with two decimal places using printf() function.
7. End the program.

PROGRAM:

#include<stdio.h>
int main(){
    float p,r,si;
    scanf("%f%f%f",&p,&r,&si);
