C: 6. Decision Making If

The if-else statement in C is used to perform the operations based on some specific condition. The operations specified in if block are executed if and only if the given condition is true. 

There are the following variants of if statement in C language.

If statement

An if statement consists of a Boolean expression followed by one or more statements

Syntax:-

if(expression){  

//code to be executed  
}  
Exercises:- 
The if-else statement is used to perform two operations for a single condition. The if-else statement is an extension to the if statement using which, we can perform two different operations, i.e., one is for the correctness of that condition, and the other is for the incorrectness of the condition.

Syntax:-
if(expression){  
//code to be executed if condition is true  
}else{  
//code to be executed if condition is false  
}  

Exercises:- 
In if-else-if ladder statement, if a condition is true then the statements defined in the if block will be executed, otherwise if some other condition is true then the statements defined in the else-if block will be executed, at the last if none of the condition is true then the statements defined in the else block will be executed.

Syntax:-
if(condition1){  
//code to be executed if condition1 is true  
}else if(condition2){  
//code to be executed if condition2 is true  
}  
else if(condition3){  
//code to be executed if condition3 is true  
}  
...  
else{  
//code to be executed if all the conditions are false  
}

C++: 7. Inheritance

In C++, inheritance is a process in which one object acquires all the properties and behaviors of its parent object automatically. In such way, you can reuse, extend or modify the attributes and behaviors which are defined in other class. In C++, the class which inherits the members of another class is called derived class and the class whose members are inherited is called base class. The derived class is the specialized class for the base class. Single Level Inheritance When one class inherits another class, it is known as single level inheritance. Example:-  #include <iostream>   using namespace std;    class Account {      public:      float salary = 60000;     };      class Programmer: public Account {      public:      float bonus = 5000;        };        int main(void) {   ...

Py: 2. Python Fundamentals

 Variable:-  Variable is a name that is used to refer to memory location. In Python, we don't need to specify the type of variable because Python is smart enough to get variable type.  Variable names can be any length can have uppercase, lowercase (A to Z, a to z), the digit (0-9), and underscore character(_). Syntax:-  num= 345 name= "mohit" Variable Types:- Number (Int, Float) Sting Boolean Get the Type of the variable:- x = 5 y = "John" print(type(x)) print(type(y)) Output:-  <class 'int'> <class 'str'> Operators:-  The operator can be defined as a symbol which is responsible for a particular operation between two operands. Python provides a variety of operators, which are described as follows. Arithmetic Operators:-  Assume variable a holds 10 and variable b holds 20, then − + Addition Adds values on either side of the operator. a + b = 30 - Subtraction Subtracts right hand operand from left hand operand. a – b = -10 * Multiplicat...
