Aim:
To write a program in c++ for fraction manipulation using operator overloading.
Algorithm:
Step 1:start the process.
Step 2:declare a class fract.
Step 3: declare the constructor fract and fract(int n,int d).
Step 4:declare the function such as void read() void Tostring().
Step 5:enter the choice for:
1. Addition
2. Subtraction
3. Multiplication
4. Division.
5. Comparing
Step 6: get the choice from the user and do the required calculation or operation.
Step 7: print the output ,save the program and exit.
