Introduction to C++

1. Basics

2. Variables

Types of Variables Identifiers User Input Strings Simple Math Not Simple Math Increment (Prefix and Postfix)Constant Challenge

3. Conditional Statements

Booleans If Expression More Logical Operators Else Expression Else If Expression Short Forms Challenge Switch Statement The Keyword Default

4. Loops

While Loop Do/While Loop For Loop Break/Continue Statements

5. Intro to Arrays

Basic Concept of the Array Loops in Arrays Manipulations with Arrays Challenge

Manipulations with Arrays

You can also use for loops in arrays to find the sum of all elements:


              12345678
            
int numbers[4] = {42, 12, 56, 98};
int sum = 0;

for (int i = 0; i <= 3; i++) {
    sum += numbers[i];
}

cout << sum;

Here the variable sum will store the sum of all elements, initially, it’s equal to 0. Then we iterate through the array using for loops and add each element to the variable sum.

You can also store in arrays the data from the user:


              12345678
            
int numbers[4];
int sum = 0;

for (int i = 0; i <= 3; i++) {
    cout << "Type the number: ";
    cin >> numbers[i];
    sum += numbers[i];
}

Tarea

Find the multiplication of 10 elements printed by the user. Store the result in the variable mul. Pay attention that the initial value of the variable mul is 1, since multiplication by 1 does not affect the result.

Take input from the user.
Multiply the user's number and the variable mul. Store the result in the variable mul.
Print the variable mul.

Please, don’t forget to type the semicolon ; at the end of the lines.
