Please answer the following questions in C program 3 a Write

Please answer the following questions in C program.

3. a. Write a program that stores the string \"Hooray for All of Us\" in an array named strng. Use the declaration char string [] = \"Hooray for All of Us\";, which ensures that the end-of-string escape sequence \\0 is included in the array. Display the characters in the array by changing the address in a pointer called messPtr. Use a for statement in your program.

b. Modify the program written in 3a to use the while statement while (*messPtr ! \'\\0\').

c. Modify the program written in 3a to start the display with the word All.

Solution

The code of all the three parts in c language are given below-

a-

#include <stdio.h>

#include <string.h>

int main() {

int i,length;

char strng[50] ={\'H\', \'o\', \'o\', \'r\', \'a\', \'y\', \'f\', \'o\', \'r\', \'A\', \'l\', \'l\', \'o\', \'f\', \'U\', \'s\', \'\\0\'};  

char *messPtr = strng;

   length = strlen(strng);

for (i=0; i<length; i++)

{

printf(\"%c\", *messPtr);

messPtr++;

}

   return 0;

}

b-

#include <stdio.h>

#include <string.h>

int main() {

int i,length;

char strng[50] ={\'H\', \'o\', \'o\', \'r\', \'a\', \'y\', \'f\', \'o\', \'r\', \'A\', \'l\', \'l\', \'o\', \'f\', \'U\', \'s\', \'\\0\'};  

char *messPtr = strng;

   length = strlen(strng);

messPtr= messPtr+9;

while (*messPtr!= \'\\0\')

{

printf(\"%c\", *messPtr);

messPtr++;

}

   return 0;

}

c-

#include <stdio.h>

#include <string.h>

int main() {

int i,length;

char strng[50] ={\'H\', \'o\', \'o\', \'r\', \'a\', \'y\', \'f\', \'o\', \'r\', \'A\', \'l\', \'l\', \'o\', \'f\', \'U\', \'s\', \'\\0\'};  

char *messPtr = strng;

   length = strlen(strng);

messPtr= messPtr+9;

for (i=0; i<length; i++)

{

printf(\"%c\", *messPtr);

messPtr++;

}

   return 0;

}
