This video tutorial explains the concept of ‘if’ and ‘recursive if’ conditions in programming. The instructor uses practical examples to demonstrate how these conditions work and how they can be implemented in code. The video is particularly useful for individuals learning programming or those who want to understand the logic behind ‘if’ conditions.
- Introduction to ‘if’ condition: The instructor starts by explaining the concept of ‘if’ condition. It is used to execute a particular code only if a certain condition is met. If the condition is not met, the program can execute a different set of instructions.
- Example of ‘if’ condition: The instructor demonstrates an example where a program is written to identify whether a given number is even or odd. The program uses the ‘if’ condition to check the remainder of the number when divided by 2. If the remainder is 0, it is an even number; if the remainder is 1, it is an odd number.
- Using parameters instead of hardcoding values: To make the program more dynamic and user-friendly, the instructor replaces the hardcoded values with parameters. This allows the user to input the number to be checked directly on the selection screen, instead of changing the value in the code each time.
- Introduction to ‘recursive if’ condition: The instructor introduces the concept of ‘recursive if’ condition, which involves using multiple ‘if’ statements. This is useful when the program needs to check multiple conditions.
- Example of ‘recursive if’ condition: The instructor demonstrates an example where a program is written to print the name of a month based on the number input by the user. The program uses multiple ‘if’ statements to check the input number and print the corresponding month. If the input number is not between 1 and 12, the program prints ‘invalid month number’.
