Which of the following statements is NOT true about if-else statement in C?

Explanation:

The given statement, "An if-else statement cannot be nested inside another if-else statement," is NOT true about the if-else statement in C. This is because in the C programming language, if-else statements can indeed be nested within each other. Nesting if-else statements means placing one or more if-else statements inside the code block of another if-else statement. This allows for the creation of more complex conditional logic structures to handle multiple conditions effectively.

Correct Option: Option 1

In C programming, nested if-else statements are used to evaluate multiple conditions in a hierarchical manner. Here's a detailed explanation:

Nested if-else Statement:

A nested if-else statement is an if-else statement that is contained within another if-else statement. This structure allows programmers to check for multiple conditions and execute different blocks of code based on the results of these conditions.

Example:

#include 

int main() {
    int x = 10;
    int y = 20;

    if (x == 10) {
        if (y == 20) {
            printf("x is 10 and y is 20\n");
        } else {
            printf("x is 10 but y is not 20\n");
        }
    } else {
        if (y == 20) {
            printf("x is not 10 but y is 20\n");
        } else {
            printf("x is not 10 and y is not 20\n");
        }
    }

    return 0;
}

In the above example, the nested if-else statements allow the program to check the values of both x and y and print appropriate messages based on their values.
