How to Read File with C

ALonon — Sun, 21 Mar 2010 14:59:25 +0000

I wrote c code to read from a file char by char. Finally, it counts char number and print it.
How to read file with C
1. Get file name to open.
2. Open file to read.
3. Get a char.
4. Print char.
5. Print total char in the file.

#include 
void main () {
	char getname[10],c=" ";
	int i=0,totalchar=0;
	FILE *mytxt;
	while(i == 0) {
		printf("Please write file name(max:10 char):\n");
		gets(getname);
		mytxt = fopen(getname,"r");
		if(mytxt == NULL)
			printf("File can not found\n");
		else {
			i=1;
			while(!feof(mytxt)) {
				c = getc(mytxt);
				if(c != EOF) {
					printf("%c",c);
					totalchar++;
				}
			}
		}
	}
    fclose(mytxt);
    printf("In %s file , there are %d chars.",getname,--totalchar);
    return 0;
}

How to learn your linux release

To learn your linux and kernel version ( release ) you can use /proc/version

Type it in console:

cat /proc/version
Linux version 2.6.18-92.el5
(brewbuilder@ls20-bc2-13.build.redhat.com)
(gcc version 4.1.2 20071124 (Red Hat 4.1.2-41))
#1 SMP Tue Apr 29 13:16:15 EDT 2008
In this output, you get to see the following information:

Exact version of the Linux kernel used in your OS: Linux version 2.6.18-92.el5

Name of the user who compiled your kernel, and also a host name where it happened: brewbuilder@ls20-bc2-13.build.redhat.com

Version of the GCC compiler used for building the kernel: gcc version 4.1.2 20071124

Type of the kernel – SMP here means Symmetric MultiProcessing kernel, the one that supports systems with multiple CPUs or multiple cpu cores

Date and time when the kernel was built: Tue Apr 29 13:16:15 EDT 2008
