String operations with examples.

Explain the various string operations with examples.

1. strupr() – This function converts a string to upper case. Syntax: strupr(str1);

Example : strupr(“mukesh rajput”)= MUKESH RAJPUT

2. strlwr() – This function converts a string to lower case. Syntax: strlwr(str1)

Example : strlwr(“CHANDIGARH”)=chandigarh

3. strlen() – This function returns the length of the string. The function returns the number of characters in the strings. Syntax: strlen(str1)

Example :  strlen(“mukesh rajput”)=13

4. strcat()- This function concatenates(combines) two or more stings in to a single string. Syntax: strcat(str1,str2)

Example : x=”muk” y=”esh” strcat(x, y)=mukesh

5. strrev()- This function reverses the string. Syntax: strrev(str1)

Example : strrev(“mukesh”)=hsekum

6. strcpy()- This function copies a string to a variable. Syntax: strcpy(str1,str2)

Example : strcpy(x,”mukesh”) x =mukesh

7. strcmp()- This function compares the two strings and returns the ASCII difference between the two strings. This is case sensitive. Syntax: strcmp(str1,str2)

Example : strcmp(“their”,”there”)=-9

8. strcmpi()- This function compares specified number of characters from both the strings and returns a value. This function is case insensitive.

Example : strcmpi(“There”,”there”)=0
