I am trying to convert an integer to a char pointer as shown below. The data results are different. I am not sure what is going wrong. Please help me in correcting the code.
int main(){
char *key1 = "/introduction";
std::ostringstream str1;
str1<< 10;
std::string data=str1.str();
std::cout <<"The data value="<<data<<std::endl; // The data value= 10
char *intro= new char[data.length()+1];
strcpy(intro, data.c_str());
std::cout <<"The data value="<<*intro <<std::endl; // The data value=1
return 0;
}
I am not sure why two data value are printed different ie, 10 and 1.
In C++, when trying to print all the contents of a char *
with cout
, you should pass the pointer, ie cout << intro << endl
.
What you've done here is dereferenced the char *
, so cout << *intro << endl
is equivalent to cout << intro[0] << endl
, which is equivalent to printing the first character, 1
.
