These are part of language translators
Question No: 18 ( M a r k s: 1 )
12
first multiplies 3*4 = 12 then Division 4/2 = 2
2+12-2 = 12
Question No: 19 ( M a r k s: 2 )
Write a declaration statement for an array of 10 elements of type float. Include an initialization statement of the first four elements to 1.0, 2.0, 3.0 and 4.0.
float tmp [10] = {1.0,2.0,3.0,4.0};
Question No: 20 ( M a r k s: 3 )
Write down the output of the following code?
int array[7], sum = 0;
for(int i=0;i<7;i++)
{
array[i] = i;
sum+= array[i];
}
cout<< “ Sum = “ <<sum;
answer: 21
Loop will run times starts from zero and add values from 1 to 6 which is equal to 21
What will be the output of the following segment of C++ code?
int A[5] = {1 , 2, 3, 4};
int i;
for (i=0; i<5; i++)
{
A[i] = 2*A[i];
cout << A[i] << " ";
}
2 4 6 8 0
Loops will run 5 times as its starting from zero. It will multiply the value of each item in array as last time is not initialized so it will multiply it with zero to give zero as output
Question No: 22 ( M a r k s: 10 )
Write a C++ program that will determine if a departmental store customer has exceeded the credit limit on a charge account.
Program should input the following facts in five variables
1. Account number
2. Balance at the beginning of month (Beginning balance)
3. total of all items charged by customer this month (charges)
4. total of all credits (credits)
5. allowed credit limit
Calculate the new balance
New balance = Beginning balance + charges – credits
Determine if new balance exceeds the allowed credit limit. For those customers whose credit limit is exceeded. The program should display the message “Credit Limit exceeded.”
