c++ - Can't read first string -

here code

#include<iostream> #include<cstring> #define limit 25 using namespace std;  int main() {     int te; //number of test cases     cin>>te;       while(te)     {      char m[limit];     char w[limit];      cin.getline(m,limit); // line not getting executed reason     cin.getline(w,limit);      cout<<"m "<<m<<" "<<endl<<"w "<<w<<endl;      te--;      }  } 

for god knows reason, machine refuses read m first test case. reads , prints values both m , w in other cases, first case, refuses read m.

sample:

input 1 hello   m  w hello   2  hello m  w  hello  stack overflow  m  stack w overflow 

cin>>te; 

this extract 1 input stream , stop @ not extract \n. you'll need ignore() character, otherwise next line extraction read empty line.

cin.ignore(); 

or ignore all characters , including next \n character (in case inputs 1foo or something), can do:

cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');
