Revision 1 Nouf almunyif
Pseudocode & Flowcharts 2 Nouf almunyif
Example 1 3 Draw a flowchart for a program that calculates the Zakat, where the user enter the amount of money then the program show the zakat. Zakat =(2.5/100) * amount. Zakat is not calculated if the amount is less than 1000 S.R Nouf almunyif
Solution 4 Input amount. Processing Check if amount is below 1000 Zakat =0. Check if amount is above 1000 Zakat =(2.5/100) * amount Output Zakat Nouf almunyif
Solution 5 Start Read amount yes no Amount > 1000 Zakat=0. Zakat=(2.5/100)*amount Print Zakat Nouf almunyif End
Example 2 6 Draw a flowchart to find the sum of first 50 natural numbers. 1+2+3+ .. +50 Nouf almunyif

Example 19 Write a code that read x and change its value as follows: If x is even, divide x by 2. If x is odd, multiply x by 3 and subtract 1. Nouf almunyif

Branching if syntax 22 if (testExpression1) { // statements to be executed if testExpression1 is true } else if(testExpression2) { // statements to be executed if testExpression1 is false // and testExpression2 is true } else if (testExpression 3) { // statements to be executed if testExpression1 //and testExpression2 is false and testExpression3 is true } . . else { // statements to be executed if all test expressions are false } Nouf almunyif

Conditional operator ?: 31 if condition is true ? then X return value : otherwise Y value; Exercise: Write a code that test whether an integer variable score contains a valid test score. Valid test scores are in the range from 0 to 100. Nouf almunyif
Conditional operator ?: if condition is true ? then X return value : otherwise Y value; 32 Nouf almunyif
switch...case Statement Syntax 33 switch (n) { case constant1: // code to be executed if n is equal to constant1; break; case constant2: // code to be executed if n is equal to constant2; break; . . . default: // code to be executed if n doesn't match any constant } Nouf almunyif
