What are the different selection structures in the C programming language?
Answer:
SELECTION STRUCTURES
Selection statements allow you to control the flow of program execution on the basis of the outcome of an expression.
different selection structures are:
1)if statements
2)if-else statements
3)if-else-if statements
4)switch statements
Explanation:
THE IF STATEMENTS
the first statement in the if block is only executed when the specified condition is true.If the condition is false then the contained statement will be skipped and execution continued with the rest of the program.
example:
public class IfDemo
{
public static void main(String[] args) {
int age;
Scanner inputDevice = new Scanner(System.in);
System.out.print("Please enter Age: ");
age = inputDevice.nextInt();
if(age > 18)
System.out.println("above 18 ");
}
}
THE IF-ELSE STATEMENTS
if the specified condition in the if statement is false, then the statement after else will be executed.
example:
public class IfElseDemo
{
public static void main( String[] args )
{
int age;
Scanner inputDevice = new Scanner( System.in );
System.out.print( "Please enter Age: " );
age = inputDevice.nextInt();
if ( age >= 18 )
System.out.println( "above 18 " );
else
System.out.println( "below 18" );
}
}
THE IF-ELSE-IF STATEMENTS
the statements after else can be another if or if-else statement, multiple if-else statements.When the condition is true, the associated statement will be executed and remaining conditions will be bypassed.
example:
public class IfElseIfDemo
{
public static void main( String[] args )
{
int age;
Scanner inputDevice = new Scanner( System.in );
System.out.print( "Please enter Age: " );
age = inputDevice.nextInt();
if ( age >= 18 && age <=35 )
System.out.println( "between 18-35 " );
else if(age >35 && age <=60)
System.out.println("between 36-60");
else
System.out.println( "not matched" );
}
}
THE SWITCH STATEMENTS
It is a multi way branch statement. It defines multiple paths of execution of a program.It provides a better alternative than if-else-if statements.
example:
public class SwitchDemo
{
public static void main( String[] args )
{
int age;
Scanner inputDevice = new Scanner( System.in );
System.out.print( "Please enter Age: " );
age = inputDevice.nextInt();
switch ( age )
{
case 18:
System.out.println( "age 18" );
break;
case 19:
System.out.println( "age 19" );
break;
default:
System.out.println( "not matched" );
break;
}
}
}
The different types of selection structures in the C programming language are:
1) if statements2) if-else statements3) if-else-if statements4) switch statementsWhat is C programming language?The sequence statement, selection statements (of which there are three variants: if, if...else, and switch), and repetition statements are the only three forms of control structures available in C++.
Due to the fact that C is compiled, it is a quicker language than Python. Since Python programs are interpreted, they typically run more slowly than C applications. When a variable is created in C, its type must be defined, and only values of that specific type are allowed to be given to it.
Therefore, the different selections of C programming languages are
