Very Very important C Programs

Convert lowercase to uppercase character

#include<stdio.h>

#include<conio.h>

void main()

{

char ch1,ch2;

clrscr();

printf("\n Enter character in lowercase:");

scanf("%c",&ch1);

ch2=(ch1>='a'&&ch1<='z')?('A'+ch1-'a'):ch1;

printf("\n Its Equivalent Uppercase is: %c\n",ch2);

getch();

}

OUTPUT:

Enter character in lowercase: s

Its Equivalent Uppercase is: S

Convert  uppercase to lowercase character

#include<stdio.h>

#include<conio.h>

void main()

{

char ch1,ch2;

clrscr();

printf("\n Enter character in uppercase:");

scanf("%c",&ch1);

ch2=(ch1>='A'&&ch1<='Z')?('a'+ch1-'A'):ch1;

printf("\n Its Equivalent lowercase is: %c\n",ch2);

getch();

}

OUTPUT:

Enter character in Uppercase: A

Its Equivalent lowercase is: a

Write a C program using conditional operator to find greatest of two numbers

#include<stdio.h>

#include<conio.h>

void main()

{

int x,y,z;

clrscr();

printf(" Enter value of x:");

scanf("%d",&x);

printf("\n Enter value of y:");

scanf("%d",&y);

z=(x>y)?x:y;

printf("\n %d is greater number",z);

getch();

}

 

OUTPUT:  

Enter value of x:30

Enter value of y:50

50 is greater number

Write a C program using conditional operators, determine: Whether the character entered through the keyboard is a lower case alphabet or not.

#include<stdio.h>

#include<conio.h>

void main()

{

char ch;

clrscr();

printf("Enter character:");

scanf("%c",&ch);

ch>=97&&ch<=122? 

printf("Character entered is lower case"); 

printf("Character entered is not lower case");

printf("\nPress any key to exit.");

getch();

}

OUTPUT:  

Enter character: r

Character entered is lower case

Press any key to exit.

 

Write a C program to bitwise operator

#include<stdio.h>

#include<conio.h>

void main()

{

char c 1,c2,c3;

clrscr();

printf("enter value for c 1 and c2");

scanf("%c, %c" ,&c 1,&c2);

c3 = c 1 & c2;

printf("\n c1 & c2 = %c",c3);

c3 = c 1 | c2;

printf("\n c1| c2 = %c",c3);

c3 = c 1 ^ c2;

printf("\n i.e. c1 ^ c2 = %c",c3);

c3 = ~c1;

printf("\n compliment of c1 = %c",c3);

c3 = c1<<2;

printf("\n left shift by 2 bits c1<<2 = %c",c3);

c3 = c 1>>2;

printf("\n right shift by 2 bits c1>>2 = %c",c3);

getch();

}

Write a C program to reverse bit pattern

#include<stdio.h>

#include<conio.h>

void main()

{

char ch;

int i;

clrscr();

ch = 'd';

for(i = 128; i> 0; i = i / 2)

if(i & ch)

printf(" 1 ");

else

printf("0 ");

ch = -ch;

printf("\n ");

for(i = 128; i > 0; i = i /2)

if(i & ch)

printf(" 1 ");

else

printf("0 ");

getch();

}

OUTPUT:  

01100100

10011011

Write a C program to a bit shift example

 

#include<stdio.h>

#include<conio.h>

void main()

{

unsigned int i;

int j;

i = 1;

for(i = 0;j < 6;j++)

{

i= i<< I;

printf("Left shift %d: %d\n", j, i);

}

for(j = 0; j < 4; j++)

{

i= i» I;

printf("Right shift %d: %d\n",j, i);

}

getch();

}

OUTPUT:  

Left shift 0:2

Left shift 1:4

Left shift 2:8

Left shift 3: 16

Left shift 4:32

Left shift 5:64

Right shift 0:32

Right shift 1: 16

Right shift 2:8

Right shift 3:4
