Hi I need help with my C++ code. I need to put the code from the void functions in the functions that has pointers and nothing in main. Also I need help in fixing the step 3 with only just one loop using return 0 and return 1 using if and else thanks.

#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*);

void testStep1();

void testStep2();

void testStep3();

void testStep4();

void testStep5();

void testStep6();

int main()

{

//STEP 1

testStep1();

//STEP 2

testStep2();

//STEP 3

testStep3();

//STEP 4

testStep4();

//STEP 5

testStep5();

//STEP 6

testStep6();

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]);

}
