To write a program to find the largest of the three numbers.

ALGORITHM:

Step-1 Start the program

Step-2 Enter the three numbers

http://sudhakutty.wordpress.com/lab-program/

Step-3 Assign large to first number

step-4 Check the next number is greater then the large. If greater then assign large to next number

Step-5 Compare the next number with large

Step-6 Do the step-4

Step-7 Print the larger value of the three number

Step-8 Stop

PROGRAM:

//TO FIND THE LARGEST OF THE THREE NUMBERS

#include<stdio.h>

main()

{

float a,b,c;

printf(“\n enter the three numbers”);

scanf(“%f %f %f “,&a,&b,&c);

printf(“\n largest value is”);

if(a>b);

{

if(a>c)

printf(“\t%f”,a);

else

printf(“\n\t%f”,c);

}

else

{

if (c>b)

printf(“\n\t%f”,c);

else

printf(“\n\t %f”,b);

}

}

SAMPLE OUTPUT:

Enter the three numbers 93 43 23

The biggest of three number is 93

To write a program to generate the fibbonaci series

ALGORITHM:


Step-2 Enter the number

Step-3 Check the number whether the number is zero or not. If zero print Zero value. If not zero go further.

Step-4 Set a loop up to the given number.

Step-5 fib=fib+a;

a=b;

b=c;

Step-6 Every increment in the loop prints the value of fib.

Step-7 After the execution of the loop stops the program

#include<stdio.h>

main()

{

int num,fib=0,a=0,b=1,i;

printf(“%d\t”,fib);

}

}

}

SAMPLE INPUT AND OUTPUT

Enter the number 5

Step-4 Print the factorial of the given number

Step-5 Stop

PROGRAM:

//TO FIND THE FACTORIAL OF THE GIVEN NUMBER

#include<stdio.h>

main()

{

int fact=1,i,num;

printf(“Enter the number”);

scanf(“%d”,&num);

for(i=1;i<=num;i++)

The factorial of 5 is 120

To write a program to find the string length and concatenation of string.

ALGORITHM:


Step-2 Enter the string

Step-3 Find the string length using the function strlen()

Step-4 Print the string length of the entered string

Step-5 concatenation the two string using the function strcat()

Step-6 Print the concatenated string

Step-7 Stop

PROGRAM:

// TO FIND THE STRING LENGTH OF THE STRING

#include<stdio.h>

#include<string.h>

main()

{

char str1[50],str2[]=” WELCOME”;

int len;

printf(“Enter the string…”);

scanf(“%s”,str1);

printf(“\nThe string length of %s is %d”,str1,strlen(str1));

printf(“\nTheconcatenation string length is %d and its string is

%s”,strlen(str1),strcat(str1,str2));

}

SAMPLE OUTPUT:

Enter the string… mech

The string length of mech is 4

The concatenation string length is 17 and its string is mech WELCOME

To write a program to give the addition of two matrixes.
