2 nd Semester Diploma Programming methodology Importent Pseudo code and C program
1.Display a text
Pseudo code
Write”hello”
C program
#include<stdio.h>
main()
{
printf(“hello”);
getch();
}
2. Adding two number
Pseudo code
Declare A,B,C as integer
A=10
B=20
C=A+B
Write “The sum of A and B=”;C
C program
#include<stdio.h>
main()
{
int A=10;
int B=20;
int C=A+B;
clrscr();
printf(“The sum of A and B=”,C);
getch();
}
3. To Display a string
Pseudo code
Declare C as string
Write “Enter a string”
Input C
Write “The string is”,C
C program
#include<stdio.h>
main()
{
char c[10];
clrscr();
printf(“Enter a string\n”);
scanf(“%S”,&c);
printf(“\nThe string is %s”,c);
getch();
}
4.Temperature Conversion
Pseudo code
Declare Celsius, Fahrenheit are float
Write “Enter the value of Degree Celsius=”
Input Celsius
Set Fahrenheit=(9/5)*(Celsius+32)
Write”The value of Degree Fahrenheit=”,Fahrenheit
C program
#include<stdio.h>
main()
{
float c,f=0;
clrscr();
printf(“Enter the value of degree Celsius=”);
scanf(“%f”,&c);
f=(9/5)*(c+32);
printf(“\nThe value of degree Celsius=%f”,c);
printf(“\nThe value of degree Fahrenheit=%f”,f);
getch();
}
5. Larger Number
(iF then)
Pseudo code
Declare X,Y,Large are integer
Write “Enter two number”
Input X,Y
Set Large=X
If X<Y then
Set Large=Y
Endif
Write “The larger is”,Large
C program
#include<stdio.h>
main()
{
int X,Y,Larger;
clrscr();
printf(“Enter two numbers”);
scanf(“%d%d”,&X,&Y);
Larger=X;
if (X<Y)
Larger=Y;
printf(“The larger number is=%d”,Larger);
getch();
}
(if then else)
Pseudo code
Declare X,Y as integer
Write “Enter two number”
Input X,Y
If X>Y
Write “The large number=”,X
Else
Write “The large number=”,Y
End if
C program
#include<stdio.h>
main()
{
int X,Y;
clrscr();
printf(“Enter two number\n”);
scanf(“%d%d”,&X,&Y);
if(X>Y)
Printf(“The larger number=%d”,X);
else
printf(“The larger number=%d”,Y);
getch();
}
6.Even Checking
Pseudo code
Declare X as integer
Write “Enter a number “
Input X
If (X%2)==0
Write “The number is even”
Else
Write “The numberis odd”
End if
C program
#include<stdio.h>
main()
{
int X;
clrscr();
printf(“Enter a number\n”);
scanf(“%d”,&X);
if ((X%2)==0)
printf(“The number is even”);
else
printf(“The number is odd”);
getch();
}
7.To Disply Day name(Multiple selection structur)
Pseudo code
Declare NO as integer
Write “Enter day number”
Input NO
Select case as NO
Case 1
Write”Day name is Sunday”
Case 2
Write”Day name is Monday”
Case 3
Write “Day name is Tuesday”
Case 4
Write “Day name is Wendnesday”
Case5
Write “Day name is Thursday”
Case6
Write”Day name is Friday”
Case7
Write “Day name is Saturday”
Default
Write”NOT a valid number”
End case
C Program
#include<stdio.h>
main()
{
int NO;
clrscr();
printf(“Enter the day NO:”);
scanf(“%d”,&NO);
switch(NO)
{
case 1:
printf(“\nDay name,Sunday”);
break;
case 2:
printf(“\nDay name, Monday”);
break;
case 3:
printf(“\nDay name, Tuesday”);
break;
case 4:
printf(“\nDay name, Wednesday”);
break;
case 5:
printf(“\nDay name, Thursday”);
break;
case 6:
printf(“\nDay name, Friday”);
break;
case 7:
printf(“\nDay name, Saturday”);
break;
default:
printf(“\n NOT a valid no”);
break;
}
