c - Use fscanf to read from given line -


i want read txt file has 10 lines. file formatted on lines:

1 1 8 2 2 3 3 1 15 4 2 7

i'm trying write function read line provided int passed it. thought of using loop iterate through lines without scanning can't figure out how implement that.

my function far looks this, loop has not been implemented yet.

void process(int linenum, char *fullname)   {     int ii, num1, num2, num3;      file* f;      f = fopen(fullname, "r");      if(f==null)        {       printf("error: not open %s", fullname);       }      else     {     (ii=0 (ii = 0; ii < (linenum-1); ii++)       {       /*move through lines without scanning*/       fscanf(f, "%d %d %d", &num1, &num2, &num3);       }      printf("numbers are: %d %d %d \n",num1, num2, num3);     }   }

you done need change format specifier.the following code reads through lines preceding intended line,but ignores reads.

for (ii=0 (ii = 1; ii < (linenum-1); ii++)       {       /*move through lines without scanning*/       fscanf(f, "%*d %*d %*d%*c");       // fscanf(f, "%*d %*d %*d\n");       } fscanf(f,"%d%d%d",&num1,&num2,&num3);

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
