Im reading from a file using fgets.
And the file has the follwoing
Date: the date
Name: Bob...
Year: 1923
I use fgets to scan the line, and then display it in a text field. The problem is I dont want the 'Date:' displayed in the text field. How can I go about just taking the information I want?
Thanks

Code:char blurb[] = "Date: 10/05/83"; char *p; puts (&blurb[5]); /* Or */ p = strchr (blurb, ' '); if (p) puts(p);
When all else fails, read the instructions.
If you're posting code, use code tags: [code] /* insert code here */ [/code]
Im using the first approach. Nice and easy.
Thanks a lot.

Code:/* remove all instances of 'pat' in 'str'. note: guaranteed not to return NULL. needs: string.h */ char * remove(char * str, const char * pat) { char * ptr = str; int len = strlen(pat); while(0 != (ptr = strstr(ptr, pat))) { strcpy(ptr, ptr+len); } return str; }
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; }
>>strcpy(ptr, ptr+len);
This results in undefined behaviour, as the source and target strings overlap.
When all else fails, read the instructions.

i'm surprised anyone hasn't suggested using strtok
Code:#include <stdio.h> #include <string.h> int main (void) { char str[]="DATE: 27/02/2004"; char *p; p = str; p = strtok (p,":"); p = strtok (NULL,": "); puts(p); return 0; }
