[@shahhappy5173]

It's very useful

[@ganeshnandavarapu199]

Simply awesome

[@kamalamalarm]

In 16.49 you have said 1712 a data then for 3d it will omit 2. It is sir? I think since field width is minimum it will ignore the 3d and print 1712

[@priyabratroutray8184]

3d means it will show the integer at least using 3 spaces, so the output will be 1712

[@durgachikkala2083]

Sir if there are errors in function will compiler show them

[@karanvirsingh2830]

Yes

[@lokeshbadugu5935]

Sir,What is meant by prototype?

[@manojsrivastava8546]

Thanks

[@vanditjain3064]

sir . i have a doubt in prototype when we declare a function int gcd(int a,int b);
bt can we also change the type of arguments and function such as float gcd(int a,int b); or int gcd(float a,float b);
