If you want to store test representation of some number in a c-string (char array), your best bet would besprintf(): 1 2 3 4 5 6 7 8 9 10 11 #include <iostream>#include <cstdio>intmain() {inti = 213;charstr[20] = {0}; std::sprintf(str,"%d", i); std::cout << str...
This method uses theint()function to perform the conversion elegantly. We will put the code in atryandexceptblock to handle exceptions raised while making the required conversions. For example, defstring_to_int(s):try:temp=int(eval(str(s)))iftype(temp)==int:returntempexcept:returnval=strin...
