EXERCISE 1 (3 HOURS)

Exercise 1A

Write a program that uses four output statements to print the pattern of asterisks (*) shown below:

* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * ** * * * * * * * * * * * * * * ** * * * * * * * * * * * *

Source Code//Exercise 1A#include <stdio.h>main(){ printf("****** *** *** ******"); printf("\n****** ** * ** ******"); printf("\n ** ** ** **"); printf("\n ** ** ** **"); printf("\n****** **** ******"); printf("\n****** * ******");}

Exercise 1B

Use printf() function to write a program that prints your name, registration number, email address and telephone number.

Source Code#include<stdio.h>main(){ printf("Muhammad Muzzammil Bin Md Rasid \n"); printf("16DET13F1112 \n"); printf("[email protected] \n"); printf("017-4408184 \n"); printf("Muhammad Shahrizal Bin abdullah \n"); printf("16DET13F1082 \n"); printf("[email protected] \n"); printf("017-5613319 \n"); printf("Aliff Marican Bin Ibrahim Marican \n"); printf("16DET13F1106 \n"); printf("012-4428248 \n"); printf("[email protected] \n"); printf("Muhamad Husaini bin Hilmi \n"); printf("16DET13F1085\n"); printf("[email protected]\n"); printf("017-4236686 \n"); return 0;}

Exercise 1C

Use puts() function to write a program that prints your name, registration number, email address and telephone number.

Source Code#include<stdio.h>main(){ puts("Muhammad Muzzammil Bin Md Rasid \n"); puts("16DET13F1112 \n"); puts("[email protected] \n"); puts("017-4408184 \n"); puts("Muhammad Shahrizal Bin abdullah \n"); puts("16DET13F1082 \n"); puts("[email protected] \n"); puts("017-5613319 \n"); puts("Aliff Marican Bin Ibrahim Marican \n"); puts("16DET13F1106\n"); puts("012-4428248 \n"); puts("[email protected] \n"); puts("Muhamad Husaini bin Hilmi \n"); puts("16DET13F1085 \n"); puts("[email protected] \n"); puts("017-4236686 \n"); return 0;}

Exercise 1D

Fix the errors of the program below:

#include <stdio.h>

main(){ char addresS [200]; puts("Insert your full address: "); getchs (Address); printf ("Your address is: %k \n",address); return ();}

The output after the errors fixed is shown as below:

5

Source Code//Exercise 1D#include<stdio.h>main(){ char address[200]; puts("Insert your full address"); gets(address); printf("Your address is :\%s\n",address); return 0;}

6

Exercise 1E:

A C program contains the following statements:

#include <stdio.h>

Int I,j,k;

Write an appropriate scanf function to enter numerical values for I,j and k, assuming

(a) The values for I,j and k will be decimal integers.

7

#include<stdio.h>

main()

{ int i,j,k; printf("Insert value of i:\n"); scanf("%d",&i); printf("Insert value of j:\n"); scanf("%d",&j); printf("Insert value of k:\n"); scanf("%d",&k); return 0;

}

(b) The values I will be decimal integer, j an octal integer and k a hexadecimal integer.

8

#include<stdio.h>main(){ int i,j,k; printf("Insert value of i:\n"); scanf("%d",&i); printf("Insert value of j:\n"); scanf("%f",&j); printf("Insert value of k:\n"); scanf("%f",&k); return 0;}

(c) The values for I and j will be hexadecimal integers and k will be an octal integer.

9

#include<stdio.h>main(){ int i,j,k; printf("Insert value of i:\n"); scanf("%f",&i); printf("Insert value of j:\n"); scanf("%f",&j); printf("Insert value of k:\n"); scanf("%f",&k); return 0;}

EXERCISE 2 ( 3 HOURS)

Exercise 2A:

Write the program and get the output.

10

//Exercise 2A#include <stdio.h>

main()

{

char name [20];int num1,num2,answer;

printf("Insert your name: ");scanf("%s",&name);printf("Enter your first integer:\n");scanf("%d",&num1);printf("Enter your second integer:\n");scanf("%d",&num2);

answer=num1+num2;

printf("The sum is : %d\n",answer);return 0;}

Exercise 2B

Modify the add.c program;

i. Subtraction of num1 and num2, then display the answer

Source Code#include <stdio.h>

main()

{



answer=num1-num2;


11

ii. Multiplication of num1 and num2, then display the answer


main()

{



answer=num1*num2;


12

iii. Division of num1 and num2, then display the answer

printf("(0177+055), (0xa8-0x1ff)");

return 0;

Exercise 2D

Write a program that prompts the user to enter three numbers and then prints them vertically (each in one line), first forward and then reversed (the last one first), as shown below.

16


main()

{

printf("Enter 3 integer : \n"); printf("12 \n"); printf("56 \n"); printf("89 \n"); printf("forward order 12 -> 56 -> 89 \n"); printf("reversed order 89 <- 56 <- 12 ");

return 0;}

scanf("%f",&radius);

area = 1.33*PI*(radius*radius*radius);

printf("the volume is:%f\n",area);

volume = 4*PI*(radius*radius);

printf("the area is:%f",volume);

return 0;

}
