Question

Which statement allows you to property check the char variable code to determine if it is equal to a "C" and then output "This is a check" and then advance to a new line? The of a variable is the block in which it is defined, from the point definition to the end of the block. What is the output of the following segment of code if 10 is input by the user when asked to enter a number?

Answer 1

20. Answer Option (C) Explanation: If (code 'C) Cout<ぐThis is a check in'' C it is the syntax to write single character.

21. Answer Option (a) Explanation: Scope of a variable is defining its lifetime. For example void p) int n; scope ofn n-11; void main() int n-10 printf("%d", n); output: 10 in pO , n is 11, which is not affect the value on n (10) in main after calling p because it's scope(a-11) only on pO function.

22. Answer. Option (e) Explanation: When user enter the value 10, it will not match with any case in the switch block, and the control goes to the default part, which gives the following output: Total-total+ 4 = 0 + 4-4 Here the output

#include <iostream> using namespace std; int main() int num, int total-0; cout << "Enter number from 1 to 10" << endl; cin>>num; switch(num) | case 1: total-1; break; case 2: total-5; break; case 3 total-10; break; case 4: total+3; break; case 8: total+6; break; default: total-total+4; cout<<"total-"<<total<<endl; return 0;

sh-4.3$ g++ -std-c++11 -o main .cpp sh-4.3$ main Enter number from 1 to 10 10 total-4 sh-4.3$
