Solution 1

Why don't you use the standard C++ library?[^].

C++

struct tm tm = {0};
char s[20]; 

tm.tm_year = ...;
tm.tm_mon = ...;
tm.tm_mday = ...;

strftime(s, 20, "%F %H:%M:%S", &tm);

Looks like a muddleheadedness:

> Like 6pm will be 18.

C++

// else if((a[8]=='P' || a[8]==P) && (a[0]==0) && (a[1]==1 || a[1]=='2' || a[1]=='3' || a[1]=='4' || a[1]=='5' || a[1]=='7' || a[1]==7))

 else if((a[8]=='P' || a[8]==P) && (a[0]==0) && (a[1]==1 || a[1]=='2' || a[1]=='3' || a[1]=='4' || a[1]=='5' || a[1]=='6' || a[1]=='7'))

Your string operations are very confusing and should be slow. You better use the std::string class with its nice functions like for input.

If something in your code is unclear you should set a break point and use the debugger.

tips:
a) use identions for better readability
b) you better write some comments in your code to make it better understandable.
c) overwriting input data is not a good idea, generate a output string.
