Implement two functions in C language:

stringLength() - Takes a pointer to a string, and a pointer toan int variable. It computes the length of the string and updatesthe int variable with the length.

stringCopy() - Copies one string onto another using pointers

#include

#define MAX_STR_LEN 2048

void stringLength(char *str,int *len)

{

// This function computes the length of the string

// at the address in the pointer *str. Once thelength

// has been determined, it updates the length

// variable OUTSIDE this function whose address is

// given by the pointer *len

//

// Note - the length can not be more thanMAX_STR_LEN

// TO DO:

// Complete this function!

// YOU ARE NOT ALLOWED TO USE FUNCTIONS FROM THE STRINGLIBRARY

}

void stringCopy(char *destStr,char *srcStr)

{

// This function copies the contents of a string whoseaddress

// is given by the pointer *srcStr to the string whoseaddress

// is given by the pointer *destStr.

// Note that the function should never try to copy morethan

// MAX_STR_LEN characters

// TO DO:

// Complete this function!

// YOU ARE NOT ALLOWED TO USE FUNCTIONS IN THE STRINGLIBRARY

}

int main()

{

char string1[MAX_STR_LEN]=\"To see a world in agrain of sand,\";

char string2[MAX_STR_LEN]=\"And a heaven in awild flower.\";

int len1,len2;

len1=0;

len2=0;

printf(\"%s\n\",string1);

printf(\"%s\n\",string2);

// DO NOT CHANGE ANYTHING ABOVE THIS LINE formain()

// In the space below, complete the code for eachstep

// 1 - Update len1 and len2 with the length of the

// corresponding strings (complete thestringLength()

// function for this!)

// DO NOT CHANGE THE PRINT STATEMENTS BELOW

printf(\"String 1 is %d characters long\n\",len1);

printf(\"String 2 is %d characters long\n\",len2);

// 2 - Copy string1 to string2 (after you do this,string2

// should contain 'To see a world in a grain ofsand,'

// complete the function stringCopy() for this part

// DO NOT CHANGE ANYTHING BELOW THIS LINE

printf(\"%s\n\",string1);

printf(\"%s\n\",string2);

return 0;
