The contents of this chapter include all of the following: Nested if else statement, logical operator in C, how logical operator can be used to make compound conditions, conditional operator, nested conditional operator, nested if-else, nested conditional operator, loops. | CSC103: Introduction to Computer and Programming Lecture No 9 Previous Lecture Nested if else statement Logical operator in C How logical operator can be used to make compound conditions Conditional operator Today’s lecture outline Nested conditional operator Example programs – nested if-else nested conditional operator Loops while loop Nested conditional operator (expression 1 ? expression 2 : expression 3); Single condition or compound condition (expression 1 ? expression 2 : expression 3); (expression 1 ? expression 2 : expression 3); Example program main( ) { float sal ; printf ("Enter the salary" ) ; scanf ( "%f", &sal ) ; if ( sal 25000 ) printf ( "Manager" ) ; else if ( sal 15000 ) printf ( "Accountant" ) ; else printf ( "Clerk" ) ; } Cont. main( ) { float sal ; printf ("Enter the salary" ) ; scanf ( "%f", &sal ) ; ( (sal 25000) ? printf ( "Manager" ) : (( sal 15000 ) ? printf ( "Accountant") : printf ( "Clerk" ) )); } Example program 1 Three numbers x, y, z are input through the keyboard, write a program to determine the smallest of the three. Write a program Example program 2 Any character is entered through the keyboard, write a program to determine whether the character entered is a capital letter, a small case letter, a digit or a special symbol. Write a program Loops in C Three major loops structures in C while loop for loop do while Loop in general Loop has a termination point finite loop Loop execution stops when the loop condition becomes false Loop has a counter that counts number of iterations of that loop Loop has a statement or a set of statements that are executed until the loop condition become false Formula 1 car race There is a path/track Each car has to complete a certain no of rounds say 10 In each round, when a car cross the finish line the condition is check whether the car has completed total no of round or not. Repetition - Example General form while loop The while . | CSC103: Introduction to Computer and Programming Lecture No 9 Previous Lecture Nested if else statement Logical operator in C How logical operator can be used to make compound conditions Conditional operator Today’s lecture outline Nested conditional operator Example programs – nested if-else nested conditional operator Loops while loop Nested conditional operator (expression 1 ? expression 2 : expression 3); Single condition or compound condition (expression 1 ? expression 2 : expression 3); (expression 1 ? expression 2 : expression 3); Example program main( ) { float sal ; printf ("Enter the salary" ) ; scanf ( "%f", &sal ) ; if ( sal 25000 ) printf ( "Manager" ) ; else if ( sal 15000 ) printf ( "Accountant" ) ; else printf ( "Clerk" ) ; } Cont. main( ) { float sal ; printf ("Enter the salary" ) ; scanf ( "%f", &sal ) ; ( (sal 25000) ? printf ( "Manager" ) : (( sal 15000 ) ? printf ( "Accountant") : printf ( "Clerk"
