Code:char line[50]; fgets(line, sizeof(line), stdin);
The fgets get the cahr but i printf it, it containt many space...then how ?.........i only want the char and the space between them but not after them got many space
Eg ..i store GOOD thing
2nd i store ddd
but my result printed out is
GOOD thing ddd

Sorry after the good thing ................ddd
..... = space
Hmm...I don't understand your program just yet, but i CAN tell you that
1)fscanf() will stop at the first space!
2)fgets(des, sizeof(des), stdin) should be:
fgets(des, strlen(des), stdin);
Code:#include <cmath> #include <complex> bool euler_flip(bool value) { return std::pow ( std::complex<float>(std::exp(1.0)), std::complex<float>(0, 1) * std::complex<float>(std::atan(1.0) *(1 << (value + 2))) ).real() < 0; }
The fgets , ...and other how to use
can some one give me some example or .teach me how to use ?
Sebastiani:
2)fgets(des, sizeof(des), stdin) should be:
fgets(des, strlen(des), stdin);
That is completely wrong.
if you did this:
des[0] = 0;
then used your code, then nothing would be stored in the string. it should be
fgets(des, sizeof(des), stdin);
Then if you want to break the string up into separate words, then use the strtok() function
