Practicals

This Page provides the solution of various practicals of Fundamental of computer programming

Write a program to calculate Simple Interest SI = (P * R * N)/100; Where, P = principle amount, R = Rate of interest, N = Period.

// Program to calculate Simple interest

#include<stdio.h>

#include<conio.h>

void main()

{

      int P,R,N;

      float SI;

      //Enters value of Principal amount Rate and Periods (Input Section)

      printf("Enter value"); /*This line is not medentory its only

                  used for your redablilty to pass inputs*/

      scanf("%d%d%d",&P,&R,&N); //Variables are case sensitive P and p both are diffrent

      // After passing inputs write logic if any

      // In this programme logic is to calculate Simple Interest

      SI=(P*R*N)/100;  //Logic

      //After logic display the value into the screen (Output Section)

      printf("Simple Rate is %f",SI);

      getch();

}

 Write a program to compute a volume of a cylinder. Use symbolic constant.

#include<stdio.h>

#include<conio.h>

#define PI 3.1472    // Capital is not compulsory but you should                          //you capital latter in #define statement

void main()

{

  int r,h;

  float V;

  clrscr(); // Clear previous screen

  //Input value of r and h by scanf function

  scanf("%d%d",&r,&h);

  //Wirte down logic

  V=PI*r*r*h;

  printf("\t***********************************");

  printf("\n\tVolume of Cylinder is %f\n",V);

  printf("\t***********************************");

  getch();     // Holds the o/p screen untill you pass key from keyboard

}

Write a program to interchange value of two variables.

a)      Using third variable

b)      Without using third variable

#include<stdio.h>

#include<conio.h>

void main()

{

  int a=10,b=20,c=0;

  clrscr();

  //No need of input Because we have already assigned it at compile time

  //Logic of Swapping with 3 variable

  c=a;

  a=b;

  b=c;

  // Logic of Swapping without 3rd variable

/*     a=a+b;

  b=a-b;

  a=a-b;*/

  printf("After swapping value of a and b is %d and %d respectively",a,b);

  getch();

}

Write a program to calculate Net Salary. User has to input Basic Salary and Output should be:

Enter Basic Salary: 5000 (e.g. 5000)

Allowances:

                        DA = 70% of Basic Salary

HRA = 7% of Basic Salary

MA = 2% of Basic Salary

TA = 4% of Basic Salary

            Deduction:

                        PF = 12% of Basic Salary

                        IT = any value (e.g. 500)

            ----------------------------------------------------------------------------------------------

            Net Salary = Basic Salary + Allowances – Deduction

#include<stdio.h>

#include<conio.h>

void main()

{

int basic,it=500;

float da,ta,hra,ma,pf,net_salary; // net-salary and net salary is not allowed

clrscr();

basic=21600; //input

// Calculate allowances (It will be added into basic salary)

da=(basic*70.0)/100.0;

hra=(basic*7.0)/100.0;

ma=(basic*2.0)/100.0;

ta=(basic*2.0)/100.0;

//Calculate PF

pf=(basic*12.0)/100.0;

net_salary=basic+da+hra+ma+ta-it-pf;

printf("%f",net_salary);

getch();

}

Write a program which scans the age in years and prints it in seconds.

#include<stdio.h>

#include<conio.h>

 main()

{

     int age;

     long int second= 1314000;

                /* here if you going to convert age into second you

                have to take data type of second as long int because

                range of the int variable is from -32768 to 32767. So

                it may possible that value of second wiil be exceed to 32767*/

//   clrscr();

     age=1;

     second=age*365*60*60;

     printf("\t%ld",second); //control string for long int is %ld

       //  printf("  %d",sizeof(long int));

     //getch();

}

Write a program to print the ASCII value of a given character and vice-versa.

#include<stdio.h>

#include<conio.h>

void main()

{

int number;

char ch;

ch='A';

clrscr();

printf("ASCII value of given character is %d",ch);

number=66;

printf("\n\n%d has equivalent ASCII value is %c",number,number);

getch();

}
