Question
What is the output of the following program lines, when embedded in a correct program that declares all variables to be of type char?
a = 'b';
b = 'c';
c = a;
cout << a << b << c << 'c';
Answer
The output of the given program lines:
bcbc
Explanation:
- a='b' means the character 'b' is stored in the variable, a. So, the initialization of the variable a is 'b'.
- b = 'c' means the character 'c' is stored in the variable, b. So, the initialization of the variable b is 'c'.
- c=a means the initilization value of the 'a' (that is is 'b') is stored in the variable, c. So, the the value of c = 'b'.
- In observed, the cout statement represents 'c'. It is print the character 'c' on the screen at end.
- Finally, the cout statement is used to print the result is 'bcbc'
Complete executable program code:
#include <iostream>
using namespace std;
int main ()
{
//Declares all variables to be
//of data type char
char a,b,c;
//Initialize the variables
a = 'b';
b = 'c';
c = a;
//Print output
cout << a << b << c << 'c';
return 0;
}
Output of the program code:
bcbc
