One, format read

1. C language

FILE * f_in = fopen ("1.txt","R"); intK; intm, N; intdp[6]; FSCANF (f_in,"%d", &k);  while(k--) {fscanf (f_in,"%d%d", &m, &N);  for(inti =0; I <4; ++i) {fscanf (f_in,"%d %d%d%d%d%d", &dp[0], &dp[1], &dp[2], &dp[3], &dp[4], &dp[5]); }    }

2. C + + >> input operators stop typing when they encounter whitespace characters, but leave whitespace characters in the buffer

Ifstream f_in ("1.txt"); intK; intm, N; intdp[6]; F_in>>K;  while(k--) {f_in>> m >>N;  for(inti =0; I <4; ++i) {f_in>> dp[0] >> dp[1] >> dp[2] >> dp[3] >> dp[4] >> dp[5]; cout<< dp[0] <<","<< dp[1] <<","<< dp[2] <<","<< dp[3] <<","<< dp[4] <<","<< dp[5] <<Endl; }    }

Second, read a line

C++

Getline always reads newline characters, reads line breaks from input cache and discards newline characters

    Ifstream f_in ("1.txt");         string str;          while (Getline (f_in, str)) {            << str << Endl;    }    

C language Fgets read and discard newline characters.

file* f_in = fopen ("1.txt""R");         Char str[1024x768];      while 1024x768 , f_in)) {        << str;    }
