2. Write a program in C to find the maximum number among given three numbers using nested if else statements only.

Objective:
The objective of this program is to determine the largest number among three input numbers using nested if else statements in the C programming language. By utilizing nested if else statements, we can compare the numbers and identify the maximum value efficiently.
Agenda:
The agenda of this program is to guide the user through the process of writing a C program that can analyse three input numbers and determine which one is the largest. By explaining the logic behind nested if else statements and their role in decision-making, the user will gain a better understanding of how to implement this functionality in their own programs.
Purpose:
The purpose of creating a program to find the maximum number among three given numbers using nested if else statements is to demonstrate the use of conditional statements in programming. By employing nested if else statements, we can compare multiple values and make decisions based on specific conditions. This program serves as a practical example of how to implement decision-making logic in C programming, showcasing the versatility and power of conditional statements.
Real-Life Applications:
In real-life scenarios, the concept of finding the maximum number among multiple values is commonly encountered in various fields such as finance, data analysis, and engineering. For instance, in financial analysis, determining the highest stock price among a set of companies can help investors make informed decisions. Similarly, in data analysis, identifying the largest data point in a dataset can provide valuable insights into trends and patterns. By mastering the skill of finding the maximum number using nested if else statements, programmers can apply this knowledge to solve real-world problems efficiently.
Validate or check weather a given number is positive or negative using the if statement.

}

return 0;
}

a program in C to find the maximum number among given three numbers using nested if else statements only.

Output:
Enter any three numbers:
50
70
30
70 is the largest number.

Explanation
Include the #include<stdio.h> Standard Input-Output Library header file to ensures that the functions for input and output processes are accessible.
int main() function definition starts the execution of the program.
then subsequently we declare a variable n1,n2 and n3 to store a number provided by the user.
The first program asks the user to enter any three number.
Then use nested "if" statements to compare numbers and decide the largest number.
The outside if statement checks whether the number n1 is greater than or equal to the number n2.
If that evaluates to true then it also checks whether n1 is greater than or equal to n3 and prints the result consequently.
If n1 is not greater, the program checks whether n2 is greater than or equal to n3 and prints the result consequently.
Finally, the program returns 0 to specify successful execution of the program.
