C++ PROGRAMMING

I/O

100

A standard input stream 

cin

200

input function for strings

getline

300

an alternate to \n

endl

400

Give at least one feature of I/O in C++.

1. type safe

2. based on streams of bytes and are device independent.

500

Differentiate I/O in C and C++

•C doesn’t have built in input/output facilities. Instead, it left the I/O to the compiler as external library functions such as printf/scanf in stdio.h library.

•Likewise, C++ continues this approach and formalizes IO in iostream and fstream libraries.

ARRAYS

100

Used to store multiple values in a single variable, instead of declaring separate variables for each value.

Arrays

200

Write an array that inputs 5 instances of the myName variable

string myName[5];

300

Declare a variable that holds an array (x) of 4 integers with values inside the array.

int x[4] = {1,2,3,4};

400

What is the output of the ff code?

int main(){

int num[3] = {20,30,50};

cout<<num[3];

return 0;}

NOTHING/ERROR

num[0] = 20;

num[1] = 30;

num[2] = 50;

500

Explain how to access the Elements on an array.

■You access an array element by referring to the index number inside square brackets [].

■Array indexes start with 0: [0] is the first element. [1] is the second element, etc.

LOOPS

100

It can execute a block of code as long as a specified condition is reached.

Loops

200

•The loop that loops through a block of code as long as a specified condition is true.

While Loops

300

•The loop that is a variant of the while loop. This loop will execute the code block once, before checking if the condition is true, then it will repeat the loop as long as the condition is true.

do/while loop

400

Write the syntax of the while loop. 

while (condition) {
// code block to be executed
}

500

Write the syntax of the For Loop

for (statement 1; statement 2; statement 3) {
// code block to be executed
}

CONDITIONS/SWITCH

100

Use ___ to specify a block of code to be executed, if a specified condition is true

if

200

Use ____ to specify a new condition to test, if the first condition is false

else if

300

Use the ____ statement to select one  of many code blocks to be executed.

switch

400

write the syntax in writing the if else statements

if (condition) {
// block of code to be executed if the condition is true
} else {
// block of code to be executed if the condition is false
}

500

Write the syntax for switch statements.

switch(expression) {
case x:
// code block
break;
case y:
// code block
break;
default:
// code block
}

MISC

100

•A COMPUTATIONAL DEVICE WHICH IS USED TO PROCESS THE DATA UNDER THE CONTROL OF A COMPUTER PROGRAM.

COMPUTER

200

Sequence of Instruction along with data.

Program

300

•One of the first programming languages that is introduced to the public

FORTRAN

400

Differentiate Computer Programming and Web Programming 

Computer programming are used to operate computers while Web programming are used to design websites and pages.

4 Things to Know Before you Code in C++

1.C++ cannot be learnt in a day

2.Learning C++ can be hard

3.No, you don’t need to learn C before C++

4.Don’t wait for the next C++ release
