concatenation of two strings

 

EX.NO:3.f                        CONCATENATION OF TWOSTRINGS

 

Aim:

To write a shell program to concatenate two strings.

 

Algorithm:

Step1: Enter into the vi editor and go to the insert mode for entering the code

Step2: Read the first string.

Step3: Read the second string

Step4: Concatenate the two strings

Step5: Enter into the escape mode for the execution of the result and verify the output

 

 

Programcode:

echo “Enter the first string”

readstr1

echo “Enter the second string”

readstr2

echo “The concatenated string is” $str1$str2

 

Sample I/P:

 

Enter the first string: Hello

Enter the second string: World

 

Sample O/P:

 

The concatenated string is HelloWorld

 

Result:

 

Thus the shell program to concatenate two strings is executed and output is verified successfully.

 

VIVA-VOCE QUESTIONS:

 

1. What is string concatenation?

2. Which function is used to join two strings?

3. What does Strcat do in C?

 

 

 

 

 

 

EX.NO:3.g                             COMPARISON OF TWOSTRINGS

 

Aim:

To write a shell program to compare the two strings.

 

Algorithm:

 

Step1: Enter into the vi editor and go to the insert mode for entering the code Step2: Read the first string.

Step3: Read the second string

Step4: Compare the two strings using the if loop

Step5: If the condition satisfies then print that two strings are equal else print two strings are not equal.

Step6: Enter into the escape mode for the execution of the result and verify the output.

 

 

Programcode:

 

”

echo “Enter first string”

readstr1

echo “Enter second string”

readstr2

 if [ $str1 = $str2 ]

 then

echo “The two strings are equal

else

echo “The two strings are not equal”

 fi

 

 

 

 

 

 

 

Sample I/P:1

Enter first string: hai

Enter second string: hai

Sample O/P:1

The two strings are equal

Sample I/P:2

Enter first string: hai

Enter second string: cse

Sample O/P:2

The two strings are not equal

 

 

Result:

Thus the shell program to compare the two strings is executed and output is verified successfully.

 

VIVA-VOCE QUESTIONS:

 

1. How to compare two strins in c?

2. What is stricmp() in C?
