You post 376 lines of code and don't tell us what the problem is?

You really should be able to do this with one while loop and one for loop. The while loop reads the file and the for loop takes care of the number of entries. I tried playing with your code and came up with this, its hard coded to a four …

Not really sure how this is a "brain teaser in C".

Because with virtual memory every user process gets the same address range but different physical memory links...so every process appears to have the same memory but in reality it has its own copy of things like data...Note: most programs will shared some blocks of code i.e. Dlls and the text …

It really depends on what and how you wrote your code...Could we see it so as to make an informed decision.

I would investigate the functions strtok() and strtof(), strtod(), strtold().

I tried single quotes in your quoted string...it appears to work [CODE] #include <stdlib.h> #include <stdio.h> #include <string.h> int main () { char *ca; char queryStringSet[100]; char command[100]; strcpy (command, "export QUERY_STRING="); strcpy (queryStringSet, "'a=1&b=2&c=3'"); strcat (command, queryStringSet); printf ("command = %s\n", command); system (command); ca = getenv ("QUERY_STRING"); printf …

Or you could use UDP instead of TCP. TCP doesn't guarantee packet data size only that it will get delivered in order...like you said if you want to extract individual messages then you'll have to figure out an application protocol to handle it..

I'm assuming this is a text file - Why don't you check for the newline character '\n'

I'm not sure why you need to force the users to call init()- a well commented header file or docs should suffice or is this part of the assignment requirements..

shouldn't this [CODE] sscanf(buffer, "%lf", tempFinal [/CODE] be [CODE] sscanf(buffer, "%lf", &tempFinal [/CODE]

execve info/man has really good example code towards the bottom of the topic.

Yes.. [url]http://www.daniweb.com/forums/thread252864.html[/url]

456 lines of code - That is the best you can do. You can't narrow the problem to a certain section of this program?

This cleans up the warnings/errors [CODE] #include<stdio.h> int main(){ char name[25] = "blank", rating[25] = "blank", state[25] = "blank"; int lobbyists=0, prevemploys=0, number=0; double networth=0, tarp=0, contributions=0; printf("\n\n(1)Bank name: %s\n(2)State: %s\n(3)Net worth: %f\n", name, state, networth); printf("(4)Rating: %s\n(5)TARP money: %f\n(6)Campaign contributions: %f\n", rating, tarp, contributions); printf("(7)Lobbyists in capitol: %d\n(8)Previous Employees …

Yes use fork then execlp(or one of the family of functions from exec).

Are you kidding...narrow it down to an operating system plus area of programming..

This might be right, then again I may have read your posting wrong [CODE] #include <stdio.h> #include <stdlib.h> typedef char* (*firstptr)(void); typedef firstptr (*secondptr)(void); int main(int argc, char**argv) { secondptr myarray[10]; exit(EXIT_SUCCESS); } [/CODE]

Try this, you had a typo in your array - 'a','b','c','e','d','e','f','g' - giving you excess elements plus a few more errors [CODE] #include <stdio.h> int main(int argc, char** argv) { char c[999]; char alpha[2][26]={{'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'},{'a','b','c','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z'}}; int pos[26]; int i=0; for(i=0;i<26;i++) { printf("%c\n",alpha[0][i]); } return 0; } [/CODE]
