It serves to send usually text-based information on the monitor (in currently running application, window), for instance:
...
int myVariable;
cout >> "Please enter a number: ";
cin >> myVarible;
//You entered number 5
cout << "You entered the number: " << myVariable;
...
In the application window you will see:
Please enter a number:
5
You entered the number: 5

What is the definition of cout?
COUT is an inbuilt function in c++ language. Cout is used to print something on to the standard output.
What does code is case-sensitive mean when it is all numerical?
It means that you are writing code computer generates different names for x and X, also it will understand commands or will not under stand it at all (c++: cout and Cout are different).

I am a student of class 10. I doesn't know C Language but I can tell such a program in C++ Language.... //------------------------------------ #include <iostream.h> #include <conio.h> void main() { int a,b,c,m; clrscr(); cout<<"Enter First Number: "; cin>>a; cout<<"Enter Second Number: "; cin>>b; if (a<b) m=a; if (a>b) m=b; cout<<"Enter Third Number: "; cin>>c; if (c<m) cout<<"The Largest Number is "<<m; else cout<<"The Largest Number is "<<c; getch(); }
What is c out?
most basicaly if I tell, cout is the printing statement in c++. cout<<"Hello world"; The above statement will print the sentence "hello wold". with the expression cout <<variable, the contents of variable is printed to the standard output. int variable=10; cout<<variable; The o/p will be 10..... Hope this will help u.... :)
How do you make a C plus plus program that arrange the the numbers in ascending order?
Heres something i whipped up in a hurry... This uses the Bubble Sort method found (related links) #include <iostream> using namespace std; int main(int argc, const char* argv) { int arraysize = 5; //Unsorted array size int array [] = { 5, 3, 4, 2, 1 }; //The array of numbers itself //Display the unsorted array cout << "Before: {"; for (int c=0; c <= arraysize; c++) { cout << array[c]; if (c != arraysize) { cout << ","; } } cout << "}" << endl; //Acctually sort the array int tmp=0; //Used for swaping values for (int loop=0; loop <= (arraysize - 1); loop++) { for (int c=0; c <= (arraysize - 1); c++) //The sort loop { if (array[c] > array[c + 1]) { //Swaps the two values in the array tmp = array[c]; array[c] = array[c + 1]; array[c + 1] = tmp; //Cleanup tmp = 0; } } } //Display the sorted array cout << "After: {"; for (int c=0; c <= arraysize; c++) { cout << array[c]; if (c != arraysize) { cout << ","; } } cout << "}" << endl; return 0; }
