1 Lab 2: Introduction to Computer Programming (ICP) (3:00pm to 4:30pm Computer Lab 3) Rab Nawaz Jadoon (Assistant Professor) Department of Computer Science CIIT, Abbottabad. Dated: ************************************************************************************* Tasks! Write C Programs for the followings! ************************************************************************************* Program 1: Ramsha s basic salary is input through the keyboard. His medical allowance is 40% of basic salary, and house rent allowance is 20% of basic salary. Write a program to calculate his gross salary? Program 2: The distance between two cities (in km.) is input through the keyboard. Write a program to convert and print this distance in meters, feet, inches and centimeters? Program 3: If the marks obtained by a student in five different subjects are input through the keyboard, find out the aggregate marks and percentage marks obtained by the student. Assume that the maximum marks that can be obtained by a student in each subject is 100? Program 4: Temperature of a city in Fahrenheit degrees is input through the keyboard. Write a program to convert this temperature into Centigrade degrees? Program 5: The length & breadth of a rectangle and radius of a circle are input through the keyboard. Write a program to calculate the area & perimeter of the rectangle, and the area & circumference of the circle? Program 6: Two numbers are input through the keyboard into two locations C and D. Write a program to interchange the contents of C and D?

2 Solutions: Program 1: //To calculate the Gross salary of an Employee float bp, ma, hra, grpay; printf( Enter the basic pay of the ramsha ); scanf( %f, &bp); ma=0.4*bp; hra=0.2*bp; grpay=bp+ma+hra; // sum of basic and all allowences printf( \nbasic pay is =%f, bp); printf( \nmedical Allowance is =%f, ma); printf( \ngross Salary is =%f, grpay);? Program 2: //Conversion of Distance float km, m, cm, ft, inch; printf( Enter the distance in Kilometer ); scanf( %f, &km); m= km *1000; cm = m * 100;

3 inch = cm * 2.54; ft = inch / 12; printf( \n Distance in meter = %f, m); printf( \n Distance in centimeter = %f, cm); printf( \n Distance in inches = %f, inch); printf( \n Distance in feet = %f, ft); Program 3: //Calculation of Aggregate and Percentage Marks int m1, m2, m3, m4, m5, aggr; float per; printf( Enter marks in five subjects ); scanf( %d %d %d %d %d, &m1, &m2, &m3, &m4, &m5 ); aggr = m1+m2+m3+m4+m5; per = aggr / 5; printf( \n Aggregate marks =%d, aggr); printf( \n Percentage marks =%f, per);

4 Program 4: //Conversion of Temperature from Fahrenheit to Centigrade. float fr, cent; printf( Enter temperature in (F): ); scanf( %f, &fr); cent = 5.0 / 9.0 * (fr 32); printf( \n temperature in centigrade is = %f, cent); Program 5: // Calculation of Perimeter and Area of Rectangle and Circle. Int length, breadth, radius, area1, perimeter; float area2, circum; printf( Enter Length and breadth of rectangle ); scanf( %d %d, &length, &breadth); area1 = length * breadth; perimeter = 2 * length + 2 * breadth; printf( \n Area of rectangle is = %d, area1); printf( \n Perimeter of rectangle is = %d, perimeter); printf( \nenter radius of the circle ); scanf( %d, &radius);

5 area2 = 3.14b* radius * radius; //area of circle circum = 2 * 3.14 * radius; //circumference of a circle printf( \n Area of Circle is = %f, area2); printf( \n Circumference of circle is = %f, circum); Program 6: //Interchange of contents of two Variables c and d. Int c,d,temp; printf( \nenter the number at C ); scanf( %d, &c); printf( \nenter the number at D ); scanf( %d, &d); temp = c; c = d; d = temp; printf( \n new number at location C= %d, c); printf( \n new number at location D= %d, d);

6 Home assignment! 1. Run all the above programs and practice other programs of the same by own. 2. Lot of practice is required. --- Hope for the best, ready for the worst ---
