cout<<"This"<<"is"; cout<<"a"<<"C++"; cout<<"program."; return 0;

} 1-6、#include <iostream> using namespace std; int main() {

int a,b,c; a=10; b=23; c=a+b;

cout<<"a+b="; cout<<c; cout<<endl; return 0; }

1-7#include <iostream> using namespace std; int main() {

int a,b,c;

int f(int x,int y,int z); cin>>a>>b>>c; c=f(a,b,c);

cout<<c<<endl; return 0; }

int f(int x,int y,int z) {

int m;

if (x<y) m=x; else m=y; if (z<m) m=z;

return(m); }

1-8、#include <iostream> using namespace std; int main() {

int a,b,c; cin>>a>>b; c=a+b;

cout<<"a+b="<<a+b<<endl; return 0; }
