I will write a sample program to show you:
#include
using namespace std; //This is what lets you use cin & cout
int main()
{
cout<<"Hi"; //always remember to use insertion operators (<< & >>) and quotes ("") AND ALWAYS TERMINATE YOUR LINE WITH SEMICOLON (;)
}
Hope that helped
cout<<"______": cin >>__>>__; [example cout<<"enter no."; cin>>a>>b; ]
#include<iostream.h> void main() { int l,b,h,v; cout<<"Enter length "; cin>>l; cout<<"Enter breadth "; cin>>b; cout<<"Enter Height "; cin>>h; v=l*b*h; cout<<"Volume is "<<v; }
#include<iostream> using namespace std; int main(int argc,char *argv[]){ int num1,num2; cout << "Enter the first number" << endl; cin >> num1; cout << "Enter the second number" << endl; cin >> num2; cout << "(" << num1 << " " << num2 << " )\n"; return 0; }
#include <iostream> using namespace std; int main() { int x,y; cout<<"please, enter the 1st value : "; cin>>x; cout<<"please, enter the 2nd value : "; cin>>y; cout<<endl; cout<<"the first value is : "<<x<<endl; cout<<"the second value is : "<<y<<endl; return 0; }
#include#includemain(){clrscr();coutb;cout
The most basic input/output operations can be performed with std::cin for input and std::cout for output. For example: #include<iostream> int main (void) { int n; std::cout << "Enter a number: "; std::cin >> n; std::cout << "The value " << n << " was entered!\n"; }
cin and cout are iostream objects, not keywords.
The class cin is an iostream class that abstracts stdin, allowing you to read from the stdin (console input) file. For instance: int age; cout << "How old are you? "; cin >> age; cout << "You said you were " << age " years of age " << endl;
#include<iostream> int main() { double a, b; std::cout << "Enter a number: "; std::cin >> a; std::cout << "Enter another number: "; std::cin >> b; std::cout << "Sum: " << a + b << std::endl; std::cout << "Average: " << (a + b) / 2 << std::endl; }
{char a;...cout > a;cout
#include<iostream> using namespace std; int gcf(int a, int b) { int t; while(b!=0) { t = b; b = a%b; a = t; } return a; } int main() { int a,b,c,d,e,f,g,h,i,j,k; cout<<"Enter 1st numbers: "; cin>>a; cout<<"Enter 2nd numbers: "; cin>>b; cout<<"Enter 3rd numbers: "; cin>>c; cout<<"Enter 4th numbers: "; cin>>d; cout<<"Enter 5th numbers: "; cin>>e; cout<<"Enter 6th numbers: "; cin>>f; cout<<"Enter 7th numbers: "; cin>>g; cout<<"Enter 8th numbers: "; cin>>h; cout<<"Enter 9th numbers: "; cin>>i; cout<<"Enter 10th numbers: "; cin>>j; k=gcf((((((((gcf(a,b),c),d),e),f),g),h),i),j); cout<<"The GCD of the 10 numbers is: "<<k<<endl; system("pause"); return 0; }
#include <iostream> using namespace std; int main() { int x; cout << "Enter a number: "; cin >> x; if(x % 2 == 0) { cout << x << " is even" << endl; } else { cout << x << " is odd" << endl; } char wait; cin >> wait; return 0; }
