Hello ! Good day

For copy max characters in CPP. Just take an array and read the values up to max character and then return

1 } 10 #include <iostream> 2 #include<string.h> 3 using namespace std; 4 5 char* StringCopyMax(char dest[],char source[],const int maxChars) { 6 // Read array upto maxChars 7 for(int i=0;i<maxChars; i++) { 8 dest[i] = source[i]; 9 return dest; 11 } 12 13 int main() 14-{ 15 char dest[35]; 16 std::cout << StringCopyMax(dest, "ABCDEFG",2) << std::endl; 17 cout<<StringCopyMax(dest, "ABCDEFG",20)<<endl; 18 return 0; 19} 20 9 input AB ABCDEFG .. Program finished with exit code 0 Press ENTER to exit console.

Sum of Even Number:

For this we need to take an loop and check the number is even or not by using number %2==0 condition in loop. Follow the code.

6 } 1 #include <iostream> 2 using namespace std; 3 4 int SumOfEvenNumbers (const int nums[],const int size) { 5 int sum=0; // declared locall variable for(int i=0;i<size;i++) { 7 8 if(nums[i]%2 ==0) { // checking number is even or not 9 sum+=nums[i]; // add sum to array value 10 11 12 return sum; // return sum value as a int 13 } 14 15 int main() 16-{ 17 int nums [5] = {1,2,3,4,5}; 18 std::cout << SumOfEven Numbers(nums,5) «< std::endl; 19 return 0; 20 } 21 } input 6 .Program finished with exit code 0 Press ENTER to exit console.

For String Compare We use function strcmp . It is return zero when both strings are equel . Fallow the sample code

1 8 9 } 11 #include <iostream> 2 #include <string.h> 3 using namespace std; 4. bool String Compare(const char str[],const char str2[]) { 5 6 bool compare; 7 // compare strings with strcmp function if( strcmp(str, str2)== 0 ) { compare true; // If both are equal return 1 10 else { compare false; // return o 13 } 14 return compare; 15 } 16 17 - int main() { 18 std::cout << String Compare("ABC", "abc") << std::endl; 19 cout<< StringCompare("ABC", "ABC")<<endl; 20 return; 21 } 22 input 12 > 9 PO
