Lecture 9 – Decisions (if-else)


Lecture 9 – Decisions (if-else)


if-else structure


We have another construct with which we can achieve similar functionality. That is if-else.

Syntax


if ( condition )

{

//Statements if the condition is true

}

else

{

//Statements if the condition is false

}

// This program demonstrates the use of multiple if’s

# include <stdio.h>




Output

Please enter your marks: 75

Congratulations! You’ve passed
# include <conio.h>




void main()

{

int marks;




Output

Please enter your marks: 50

Congratulations! You’ve passed

 




Output

Please enter your marks: 25

Sorry! You didn’t make it :(

clrscr();                                                                                                

printf(“\nPlease enter your marks: ”);

scanf(“%d”, &marks);

if(marks>=50)

{

printf(“\nCongratulations! You’ve passed”);

}

else

{

printf(“\nSorry! You didn’t make it :(”);

}

getch();

}

Lecture 17 – Functions (continued)

Let’s see how we can write a function which takes no argument but returns a value. Type 2 – Functions that take NO argument and returns A value I would write a function which would 1.        Ask the user to input a number 2.        Calculate its square 3.        Return the calculated value to main function 4.        Main function will display calculated result   #include <stdio.h> #include <conio.h>   void square() { int number; printf(“\nPlease enter a number :”); Output There would be no output as it has a syntax error. The error is LVALUE REQUIRED scanf(“%d”, &number); number = number * number; return number; } void main() { clrscr();         ...

Lecture 10 – Decisions (if-else-if)

if-else-if Consider a scenario where we have to check multiple conditions which are related to each other. For example we enter marks of a student and then we assign a grade to it. Marks Grade >=80 A >=70 and <80 B >=60 and <70 C >=50 and <60 D <50 Fail   In above scenario, if we use simple if then we need to use FIVE if statements. These if’s would be checked every time, even if the first condition is true. Syntax if(condition) { // Statements if true } else if (condition) { //Statements if true } else if (condition) { //Statements if true } else if (condition) { //Statements if true } else if (condition) { //Statements if true } . . else { }   With à if Example 19 - Grading system using if With à if-else-if Exam...
