Description: |
am using ms vc++ - i need as simple program to concatenate 3 wchar_t* variables into
one inside a loop. problem description is attached. it is also listed below:
I am having a problem with wchar_t* variables. If I create an initial wchar_t* by using something like:
wchar_t* InitValue = L”SM_Lst_”;
my expectation is that InitValue will have a length of 16:
• 2 bytes for each of the y characters in the string and 2 chars for the null terminator.
• sizeof(L"SM_Lst_"), in fact, returns 16
I need to construct a loop. In pseudo code it is
Int CharCount;
wchar_t* AddString = L””;
wchar_t* Name = L””;
I = 0;
while(i < 3){
AddString = I formatted as “%03d”
Name = InitString + AddString + “_n”;
CharCount = SomeFunc(Name); // which will return 26 for each iteration
i ++;
}
Here are the requirements:
1. Name will have a value of L”SM_Lst_000_n”, L”SM_Lst_001_n” and L”SM_Lst_002_n”
for each of the iterations, respectively
2. SomeFunc (e.g. wcslen, sizeof etc…) will return a CharCount value of 26
3. The app must be work in VS2022 as a Dialog based app
No need to develop the app – ie I will accept code but the code hast to work. There are an awful lot of examples on the internet that simply do not work |
