Hi, I need help with my C++ code. I need to put everything in functions not in main. Also, I need help fixing step 3 to just one loop but it needs to contain if and else, return 0 and return 1. Thanks

This is my code:

#include

using std::cout;

using std::cin;

using std::endl;

//function templates

int myStrLen(const char*);

void myStrCpy(char*, const char*);

int myStrCmp(const char*, const char*);

void myStrSwap(char*, char*);

void myStrUpr(char*);

void myStrLwr(char*);

int main()

{

//STEP 1

char step1[] = { "Star" };

cout << step1 << endl;

cout << "Length = " << myStrLen(step1) << endl << endl;

//STEP 2

char step2a[] = { "This" };

char step2b[] = { "That" };

cout << "step2a = " << step2a << endl;

cout << "step2b = " << step2b << endl;

myStrCpy(step2a, step2b);

cout << "step2a = " << step2a << endl;

cout << "step2b = " << step2b << endl << endl;

//STEP 3

char step3a[] = { "Those" };

char step3b[] = { "These" };

cout << "step3a = " << step3a << endl;

cout << "step3b = " << step3b << endl;

if (myStrCmp(step3a, step3b) == 0)

cout << "They are the same!" << endl << endl;

else

cout << "They are NOT the same!" << endl << endl;

//STEP 4

char step4a[] = { "Them" };

char step4b[] = { "They" };

cout << "step4a = " << step4a << endl;

cout << "step4b = " << step4b << endl;

myStrSwap(step4a, step4b);

cout << "step4a = " << step4a << endl;

cout << "step4b = " << step4b << endl << endl;

//STEP 5

char step5[] = { "toupper" };

cout << step5 << endl;

myStrUpr(step5);

cout << step5 << endl << endl;

//STEP 6

char step6[] = { "TOLOWER" };

cout << step6 << endl;

myStrLwr(step6);

cout << step6 << endl << endl;

system("pause");

}

//STEP 1 of 7: C - String Length Function

int myStrLen(const char* str)

{

int len = 0;

for (int i = 0; str[i] != '\0'; i++)

{

len += 1;

}

return len;

}

//STEP 2 of 7: C - String Copy Function

void myStrCpy(char* dest, const char* src)

{

int srcLen = 0;

for (int i = 0; src[i] != '\0'; i++)

{

dest[i] = src[i];

srcLen += 1;

}

dest[srcLen] = '\0';

}

//STEP 3 of 7: Write A C - String Compare Function

int myStrCmp(const char* str1, const char* str2)

{

int i = 0;

for (i = 0; str1[i] != '\0' && str2[i] != '\0'; i++)

{

if (str1[i] != str2[i])

{

return 1;

}

}

if (str1[i] == '\0' && str2[i] == '\0')

{

return 0;

}

else

{

return 1;

}

}

//STEP 4 of 7: Write A C-String Swap Function

void myStrSwap(char* str1, char* str2)

{

for (int i = 0; str1[i] != '\0' || str2[i] != '\0'; i++)

{

char temp = str1[i];

str1[i] = str2[i];

str2[i] = temp;

}

}

//STEP 5

void myStrUpr(char* str)

{

for (int i = 0; str[i] != '\0'; i++)

{

str[i] = toupper(str[i]);

}

}

//STEP 6

void myStrLwr(char* str)

{

for (int i = 0; str[i] != '\0'; i++)

{

str[i] = tolower(str[i]);

}
