Question

C++

1. Type in the above program . Before running the program, change each of the question marks to the numbers 1 through 5 indicating the order in which that line will be executed. Run the program and check your numbers. Fix and rerun if necessary. Submit the program and the output.

#include <iostream>

using namespace std;

//prototypes

void DemonstrateProc1();

void DemonstrateProc2(int num);

int main()

{

cout << "?. Execution starts with main. " << endl;

DemonstrateProc1();

      cout << "?. Then we come here. " << endl;

      DemonstrateProc2(100);

      cout << "?. Finally we come here. "<< endl;

    return 0;

}

//****************************

void DemonstrateProc1()

{

    cout << "?. This is a sample procedure." << endl;

}

//****************************

void DemonstrateProc2(int num)

{

    cout << "?. This is another sample procedure. " << endl;

      cout << "   num is an argument or parameter. " << endl;

      cout << "   The value of num is " << num << endl;

}

Answer 1

#include <iostream>

using namespace std;

//prototypes

void DemonstrateProc1();

void DemonstrateProc2(int num);

int main(){

cout << "1. Execution starts with main. " << endl;

DemonstrateProc1();

cout << "2. Then we come here. " << endl;

DemonstrateProc2(100);

cout << "3. Finally we come here. "<< endl;

return 0;

}

//****************************

void DemonstrateProc1(){

cout << "4. This is a sample procedure." << endl;

}

//****************************

void DemonstrateProc2(int num){

cout << "5. This is another sample procedure. " << endl;

cout << " num is an argument or parameter. " << endl;

cout << " The value of num is " << num << endl;

}

In main we will print the line 1 next we will call the DemonstrateProc1() and prints the line 4 next we will go back to main and prints line 2 next we are calling DemonstrateProc1(100) with argument so we will inside procedure and prints Line 5 and other 2 lines and backs to main and prints line3
