Question

Analyze following program and Find Syntax errors.

#include<iostream>

int show(int x)

int main()

{     int A,B;

      char B=10;

cout<<”Enter Value of A”;

cin<<A;

show(A)

show(50)   

      }

      cin.get();

}

int show(int x);

{

cout<<”Value is =” <<X

cout<<endl;

}

Answer 1

Analysis of Given Code :

#include<iostream> //including iostream header. iostream includes necessary information for program.

int show(int x) //declaring function of integer data type "show" by passing parameter x of integer data type

int main() //declaring main function. program execution is begins here.

{ //Entering into the main function.

int A,B; //Declaring two variables A,B of integer data type.

char B=10; //Declaring character data type variable B and assigning value 10 to B.

cout<<"Enter Value of A";//Printing "Enter Value of A".

cin<<A; //Taking input

show(A) //calling function show() by passing A value.

show(50) // calling function show() by passing value 50.

} //main function ends;

cin.get(); //reads input character

}

int show(int x); //defining function show().

{ //Entering into show function.

cout<<"Value is =" <<X //Printing value of X.

cout<<endl; //printing new line.

} //show() function ends.

Correct Code :

#include <iostream> //including iostream header. iostream includes necessary information for program.

using namespace std; //compiler uses std namespace

int show(int x); //declaring function of integer data type "show" by passing parameter x of integer data type

int main() //declaring main function. program execution is begins here.
{ //Entering into the main function.
int A,B; //Declaring two variables A,B of integer data type.

//char B=10; //it's an error because we are already declared variable B as integer data type.
cout<<endl; //printing new line.
cout<<" Enter Value of A"; //Printing "Enter Value of A".

//cin<<A; //it's an error because for cin we should use >>operator.
cin>>A; //Taking input from keyboard

show(A); //calling function show() by passing A value.

show(50); // calling function show() by passing value 50.
}

int show(int x) //defining function show().

{ //Entering into show function.

cout<<" Value is =" <<X //Printing value of X.

cout<<endl; //printing new line.

} //show() function ends.

Output :
