Question

so the void function below works to calculate the sum and average of all numbers between m and n(inclusive). The problem im having is that if i enter an M value higher than the N value, the program should output a 0. Can anyone help me with this.

}

void fun2(int m, int n)

{

int sum=((n+m)*(n-m+1)/2);

int cnt=n-m+1;

double avg=(double) sum/(double)cnt;

cout<<"for function 2, m ="<< m << " n="<< n<< " sum="<< sum << " avg="<< avg<<endl;

}

Answer 1

we can use an if statement , which checks if m>n , if it is so we print 0.

and inside the else block we can put the whole program

PROGRAM:

void fun2(int m, int n)

{
if (m>n){
cout<< 0;
}

else{
  
int sum=((n+m)*(n-m+1)/2);

int cnt=n-m+1;

double avg=(double) sum/(double)cnt;

cout<<"for function 2, m ="<< m << " n="<< n<< " sum="<< sum << " avg="<< avg<<endl;
}
}
