Formatting output to resemble a table in C++ -

i using sprintf format data. same output when formatted using printf works cannot use printf using output data send email.

for(...) {  sprintf(sluns, "%-50s%-50s%-50s%-3d%-14s", str1, str2, str3, int1, str4);  string srow(sluns);  stable = stable + "\n" + srow; } 

the output of stable looks below. width not constant columns. because converting row elements c string ?

name1      str1       str2       10         str3  name1      str1       str2       10         str3 name111      str1       str2       10         str3 

i see have c++ tag on question. i'll recommend use c++.

you can use left , setw iomanip achive want.

example:

#include <string> #include <iostream> #include <strstream> #include <iomanip>  using namespace std;  string str1 = "str1"; string str2 = "str2"; string str3 = "str3"; string str4 = "str4"; int = 10;  int main() {     strstream str;      str << left         << setw(10) << str1         << setw(10) << str2         << setw(10) << str3         << setw(10) <<         << setw(10) << str4         << endl;      cout << str.rdbuf() << endl;  }
