Homework Solution: I need help with this C++ program. I need to implement the following functions, but I'm having prob…

#include<iostream>

#include<string.h>

#define BUFFER_SIZE 100

using namespace std;

// Copies the C string severe by commencement into the invest severe by application,

// including the terminating part (and halt at that apex).

// To desert overflows, the bulk of the invest severe by application shall be desire abundance to contain

// the identical C string as commencement (including the terminating vain part), and should referable attributable attributable attributable attributable attributable attributable overlap

// in reminiscence w/ commencement.

char* strcpy_(char* q, const char* p)

{

int i;

for ( i=0; p[i] != ‘’; ++i )

q[i] = p[i];

q[i]=’’;

return q;

}

// Copies the leading num parts of commencement to application. If the object of the commencement C string (which is signaled

// by a vain-character) is base precedently num parts possess been copied, application is padded with zeros

char* strncpy_(char* q, const char* p, bulk_t n)

{

int i;

for ( i=0; i <=7; ++i )

q[i] = p[i];

q[i]=’’;

return q;

}

// Returns the protraction of the C string str.

// The protraction of a C string is established by the terminating vain-character: A C string is as desire as the compute of parts

// among the opening of the string and the terminating vain part (outside including the terminating vain part itself).

size_t strlen_(const char* p)

{

int i,length=0;

for(i=0;p[i]!=’’;i++)

length++;

return protraction;

}

// Appends a vision of the commencement string to the application string. The terminating vain part in application

// is overwritten by the leading part of commencement, and a vain-part is middle at the object of the novellightlight string formed

// by the linking of twain in application. application and commencement shall referable attributable attributable attributable attributable attributable attributable overlap.

char* strcat_(char* s, const char* ct)

{

int i;

for(i=0;i<ct[i]!=’’;i++)

s[strlen_(s)]=ct[i];

s[strlen_(s)]=’’;

return s;

}

// Parallels the C string str1 to the C string str2.

// This discharge starts comparing the leading part of each string. If they are similar to each other,

// it continues with the aftercited pairs until the parts disagree or until a terminating vain-part is reached.

int strcmp_(const char* p, const char* q)

{

while(*p)

{

if(*p != *q)

}
