Question

Trebuie sa fac media aritmetica a 3 numere, dar trebuie sa o scriu cu exact 2 zecimale(exemplu: 1.00; 8.33; 7.66).Stiti cum se face?(in c++)

Answer 1

Exemplu varianta C:
double a=1.00,b=8.33,c=7.66,s=0;
s=(a+b+c)/3;
printf("%.2f",s);

Exemplu varianta C++:
double a=1.00,b=8.33,c=7.66,s=0;
std::cout<<std::fixed;
std::cout<<std::setprecision(2);
std::cout<<s;

Answer 2

Pt zecimale folosesti float.
#include<iostream.h>
int main()
{  float m;
 int a,b,c;
cin>>a>>b>>c;
m=a+b+c;
m=m/3;
cout<<m;
}
