Your logic does not make much sense. You read a line from the file, then you are trying to use a while loop to read another line of text and compare it with the string a. You should read a line and then test if it contains the character you are looking for. However, note that you cannot set different characters to different colours. You can only use a single colour for the entire label.

Of course you must get the same answer (within rounding effects), otherwise one (or both) libraries would have been broken. THESE PEOPLE REALLY BOTHER ME!! How can they know what you should do without knowing what you want done?!?! -- C++ FQA Lite

I think you do not understand: maybe you should just forget the recursion counter - it is only a safeguard, and will not help you calculate the determinant! Please check out the link to code I posted above. It does not use recursion and therefore does not need a counter. And it might even be slightly faster. GOTOs are a bit like wire coat hangers: they tend to breed in the darkness, such that where there once were few, eventually there are many, and the program's architecture collapses beneath them.

I cant get u properly can u please ellaborate...

I can only agree with Richard. I've had a look at some of your questions and found that you're lacking the most fundamental understanding on how to properly write and test a program in C. Please do yourself and everyone else a favor and use a proper C book or tutorial. One of the first links I found on that topic is this: http://www.cprogramming.com/tutorial/c-tutorial.html[^] . Read that tutorial, take your time to understand what it teaches you. Make sure to actually try out the program snippets. Learn how to set up your working environment: compiler, linker, debugger. Once you've done that you'll save a lot of time because you won't need to ask about such basic problems. Learning C will take a considerable amount of time. But not learning it properly will cost you even more time in the long run, and others as well!

Are you sure that your project configuration includes that directory in its search path?

Best answer really... I have yet to see a "code converter" that did a good job without generating cluttered, hard to read code (that can run slow compared to if you have just done the conversion manually).

In C, you cannot define a function inside another function. All functions must stand on their own. The difficult we do right away... ...the impossible takes slightly longer.

The format %s is used to output a null terminated string. The variable it expects is a char*. I can think of 2 possibilities. Since you haven't posted any relevant code, I'm only guessing here. First guess is that you're trying to print a string and are using an extra & character - char string[20]; printf("%s", &string); // The & is not needed here. Second guess is that you've received a char** as a function argument and trying to print it. void fun(char** arg) { printf("%s", *arg); // * is needed here. } It would be best if you can post the relevant code. «_Superman_»  _I love work.

ya it is actually i was planning to make entire program as function and create another main.c that display only the output of the function..

However, the OP code is C, you know, another programming language. ;) THESE PEOPLE REALLY BOTHER ME!! How can they know what you should do without knowing what you want done?!?! -- C++ FQA Lite

hi, I don't know what's the use of summation in your code. If you want summation of float numbers generated numbers only means, the following piece of code is enough i guess.. See once srand(12345); float z=0.0; float a=0.2,y=0.0; int i; for(i=0;i<5;i++) { float b=((float)rand()/(float)(RAND_MAX))*a; printf("%f\n",b); z=z+b; } printf("summation:\\n%f\\n",z);

How do you compute the squares? This program: #include <stdio.h> int main() { double a [] = { 0.035679, 0.079935, 0.033320, 0.042424, 0.012387 }; double sum, square; int n; sum = 0.0; for (n=0; n<sizeof(a)/sizeof(a[0]); ++n) { square = a[n]*a[n]; sum += square; printf("%g ----> %g\n", a[n], square); } printf("sum of squares: %g\n", sum); return 0; } gives: 0.035679 ----> 0.00127299 0.079935 ----> 0.0063896 0.03332 ----> 0.00111022 0.042424 ----> 0.0017998 0.012387 ----> 0.000153438 sum of squares: 0.0107261 THESE PEOPLE REALLY BOTHER ME!!

thank you finally I got it..
