1: State use of branching statement in C
program.
A1:
The main branching statements in C program are:
if statement: It is used to execute a block
of code only if a specified condition is true.
if-else statement: It allows you to execute
one block of code if a condition is true and another block if the condition is
false.
switch statement: It is used to select one of many code blocks to be executed, based on the value of an expression.
2: Draw Flowchart and write syntax for if-else
statement with example.
Syntax:
if (marks >= 35) {
printf(“You
are pass.”);
}
else {
printf(“You
are fail.”);
}
3: Draw Flowchart and write syntax for nested
if-else statement with examples.
If (age >= 18) {
If
(gender == ‘m’) {
printf(“You
are an adult Man.”);
}
Else
{
printf(“You
are an adult Woman.”);
}
}
else {
printf(“You
are not adult.”);
}

4: Explain syntax of switch statement or
Demonstrate the use of switch statement with example or explain switch-case
statement with syntax. Or explain switch-case statement with suitable
example.*****
A4:
Syntax:
switch (expression)
{
case
constant1:
// statements
break;
case
constant2:
//
statements
break;
.
.
default:
//
default statements
}
Example:
switch (gender)
{
case ‘m’:
printf(“You
are male”);
break;
case ‘f’:
printf(“You are female”);
break;
default:
printf(“Enter the correct gender.”);
}
5: Differentiate between break and continue
statement or What is the use of break and continue? Explain with example. OR
explain need of decision making and difference between break and continue
statement **
Break Statement:
It is used to terminate a loop.
It is used when a certain condition is met.
The control is transferred to the first statement after the
loop when break statement execute.
It is used in switch case statement to exit the switch
block.
Continue Statement:
It is used to skip the rest of the code inside a loop.
It is often used with conditional statements to skip certain
iterations.
When a continue statement is executed, the control goes back
to the loop control expression.
6: Give the list of conditional branching
statements in C language.
if statement: It is use to execute a block of code if
a specified condition is true.
if-else statement: It provide an alternative block of
code to be executed if the condition is false.
else-if ladder: The else-if ladder allows to test
multiple conditions sequentially.
switch statement: It is used to select one of many
code blocks to be executed based on the value of an expression.

7: Explain if-else-if ladder statement with
example or explain if-else-if ladder statement with suitable example OR write
format for if-else-if ladder statement **
It allows to test multiple conditions sequentially and execute the block of
code associated with the first condition that is true.
Example:
if (marks >= 90) {
printf("Grade: A\n");
} else
if (marks >= 70) {
printf("Grade: B\n");
}
else {
printf("Grade: C\n");
}
8: Explain nested if else statement with
example. **
A nested if-else statement is an if-else statement that is nested inside
another if or else block.
if (age >= 18)
{
if
(gender == 'M')
{
printf("You are a male
adult.");
}
Else
{
printf("You are a female
adult.");
}
}
else
{
printf("You are not an
adult.");
}
9: Give difference between switch case
statement and if else statement.
1. In the if-else statement, the condition is based on a
relational or logical expression that evaluates to either true or false.
In the switch statement, the condition is based on the value
of an expression, and the control flow jumps to the corresponding case label.
2. The if-else statement allows for more complex conditions
using relational and logical operators. The switch statement is specifically
designed for comparing the equality of the expression.
3. In an if-else statement, the control flow can be more
flexible based on true condition.
In a switch statement, the control flow jumps directly to
the matching case.
4. if-else statements allow for comparisons using a wide
range of operators (>, <, >=, <=, ==, !=).
Switch statements are limited to equality comparisons (==).

10: Explain use of break statement in C
Program. OR Explain Break Statement And Continue Statement with Suitable
Example. **
Break Statement:
It is used to terminate a loop.
It is used when a certain condition is met.
The control is transferred to the first statement after the
loop when break statement execute.
It is used in switch case statement to exit the switch
block.
11: State use of go to statement in c program
OR Explain goto statement with syntax. ***
The goto statement allows you to unconditionally transfer
control to a labelled statement within the same function.
Syntax:
goto label;
// Statement(s) which
are not to be executed.
label:
// Statement(s) to
be executed.
12: The break statement used to exit from:
A12: The break statement is used to exit from loops. It is
associated with for, while, and do-while loops.
