Unformatted text preview: In the last lecture Conditional Construct if if-else Loop ­ Repetition structure Example int sum ; sum = 1+2+3+4+5+……..+10 ; cout << sum ; Find the Sum of the first 100 Integer starting from 1 ? while while ( Logical Expression ) { statements; : } int sum ; sum = 0 ; int sum = 0; ( Optional ) Example int sum , number ; sum = 0 ; number = 1 ; while ( number <= 1000 ) { sum = sum + number ; number = number + 1 ; } cout << “ The sum of the first 1000 integer starting from 1 is ” << sum ; while (number <= UpperLimit) Example int sum, number , UpperLimit ; sum = 0 ; number = 1 ; cout << “ Please enter the upper limit for which you want the sum ” ; cin >> UpperLimi t; while (number <= UpperLimit) { sum = sum + number ; number = number +1 ; } cout << “ The sum of the first ” << UpperLimit << “ integer is ” << sum ; if ( number % 2 == 0 ) { sum = sum + number ; number = number + 1 ; } Example sum = 0; number = 1; cout << “ Please enter the upper limit for which you want the sum ”; cin >> UpperLimit; while (number <= UpperLimit) { if (number % 2 == 0) { sum = sum + number; number = number + 1; } } cout << “ The sum of all even integer between 1 and ” << UpperLimit << “ is” << sum; 2 * ( number / 2 ) ; ? int Junk ; Junk = 1 ; while ( Junk <= UpperLimit ) ( infinite loop ) { sum = sum + number ; number = number + 1 ; } X Flow Chart for While Construct WHILE Statement Entry point for WHILE block While Condition is No true? Exit Process Exit point for WHILE block Factorial Definition n! = n*(n­1)*(n­2)*(n­3)…………*3*2*1 Example: Factorial #include <iostream.h> main ( ) { int number ; int factorial ; factorial = 1 ; cout << “Enter the number of Factorial” ; cin >> number ; while ( number >= 1 ) { factorial = factorial * number ; number = number – 1 ; } cout << “Factorial is” << factorial ; } Property of While Statement It executes zero or more times ...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
