Typed Code:

// including required headers
#include <stdio.h>
#include <string.h>

int main()
{
// A character Array to store Noun
char Noun[100];
// A character Array to store Plural
char Plural[100];
  
// prompt for Nouns
printf("Enter a Noun: ");
// reading a string and storing it in noun
scanf("%s",Noun);
  
// A variable to store Length of Noun
int Length=strlen(Noun);
  
// If the Last character is y
if (Noun[Length-1] == 'y')
{
// Local variable
int i=0;
// Copying Noun into Plural except the last letter
for (i = 0; i < Length-1; i++)
{
// Copying each character
Plural[i] = Noun[i];
}
//Appending the word 'ies'
Plural[i++] = 'i';
Plural[i++] = 'e';
Plural[i++] = 's';
// Appending Null character
Plural[i++] = '\0';
}
// if Noun ends with 's' or 'ch' or 'sh'
else if(Noun[Length-1] == 's' ||
(Noun[Length-2] == 'c' && Noun[Length-1] == 'h') ||
(Noun[Length-2] == 's' && Noun[Length-1] == 'h')
)
{
// Local variable
int i = 0;
// Copying Noun into Plural
for (i = 0; i < Length; i++)
{
// Copying each character
Plural[i] = Noun[i];
}
//Appending the word 'ies'
Plural[i++] = 'e';
Plural[i++] = 's';
// Appending Null character
Plural[i++] = '\0';
}
// in all other cases
else
{
  
// Local variable
int i = 0;
// Copying Noun into Plural
for (i = 0; i < Length; i++)
{
// Copying each character
Plural[i] = Noun[i];
}
// Appending 's'
Plural[i++] = 's';
// Appending Null character
Plural[i++] = '\0';
}
  
//printing Noun and its Plural
printf("%s --> %s\n", Noun, Plural);
return 0;
}
//code ended here
