Thread: Need a sample program.

I would like it if some of you can post some sample C programs. I'm testing out some color-schemes. Keep in mind this isn't my homework so it doesn't exactly have to work. The longer the better.

On the Cprogramming.com website, in the C forum, you can't find C programs?

Quickly, take a moment for prayer. You'll need all the help you can get to pass your class.

Not looking for small pieces of code i'm talking about one with hundreds of lines and a lot of functions, memory allocation, etc. I'm still new to C so I not exactly sure what can show up in C, that's why I'm testing the colorshemes to find the perfect one. Some values show up differently and functions too.

I'm also not taking a class I'm learning C for fun.

That's kind of a silly request, but here.

Go to sourceforge.net and download the source of any C project there.

Well, then here's lesson #1 ... C is not about the color schemes in your IDE's editor.

Quit messing with what does not matter and grab yourself a couple of decent books and tutorials on C programming and get on with what does...

Yeah I needed that, I have put off programming C for a while. Thanks.

Here's some simple programs I've written.

Code:

/* coffee */
#include <stdio.h>
#include <stdlib.h>

void total(int y) {
	float x = (y * 2.99);
	printf("Your total is $%0.2f.", x);
	return;
}

int main(int argc, char *argv[]) {
	int y;
	if (!argv[1]) {
		printf("How many cups of coffee would you like? ");
		scanf("%d", &y);
		total(y);
		return 0;
	}
	y = (atoi(argv[1]));
	total(y);
	return 0;
}

Code:

/* digit counter */
#include <stdio.h>

int digits(const char *p) {
	int x;
	for (x = 0; *p != '\0'; p++) {
		if (*p == '0' || *p == '1' || *p == '2' ||
		*p == '3' || *p == '4' || *p == '5' ||
		*p == '6' || *p == '7' || *p == '8' || *p == '9') x++;
	}
	return x;
}

int main() {
	int x;
	char y[256];
	printf("Enter a string: ");
	fgets(y, sizeof(y), stdin);
	x = digits(y);
	printf("That string has %d digits.\n", x);
	return 0;
}

Code:

/* spaces counter */
#include <stdio.h>

int spaces(const char *p) {
	int x;
	for (x = 0; *p != '\0'; p++)
		if (*p == ' ') x++;
	return x;
}

int main() {
	int x;
	char y[256];
	printf("Enter a string: ");
	fgets(y, sizeof(y), stdin);
	x = spaces(y);
	printf("That string has %d spaces.\n", x);
	return 0;
}

Code:

/* file reader */
#include <stdio.h>

int main(int argc, char *argv[]) {
	if (!argv[1]) {
		printf("USAGE: %s [input]\n", argv[0]);
		return 1;
	}
	int x;
	for (x = 1; x < argc; x++) {
		FILE *in = (fopen(argv[x], "r"));
		int y;
		if (in == NULL) return 2;
		while ((y = fgetc(in)) != EOF) putchar(y);
	}
	return 0;
}
