D. Short answer type questions.
1. What is the purpose of looping statements?
2. Write the names of all the jump statements provided by C++.
3. Write the syntax to declare a variable inside the for loop.
4. What is the use of goto statement in C++?
E. Long answer type questions.
1. Differentiate between break and continue statements.
2. Write any two differences between while and do-while loops.
3. Can a while loop contain another while loop? If yes, write the syntax to do the same.
F. Find the output of the following codes:
1. int num = 8;
for(int i = 1; i <= num; i++)
{
if(i==5)
continue;
else
cout<<i << “\n”;
}
2. int i = 1; 3. int sum = 0;
while(i <5) for(int i = 0; i <= 10; i++)
{ {
cout<< i; sum = sum + i;
i = i * 2; cout<< sum;
} }
4. int r = 5, c = 3;
for(int i = 1; i <= r; ++i)
{
for(int j = 1; j <= c; ++j)
{
cout<< "* ";
}
cout<<"\n";
}
