Your problem is not to convert int to char if I'm correct. You only need to check the input with

int isdigit(int character);

link (http://www.acm.uiuc.edu/webmonkeys/book/c_guide/2.2.html)

Yes. With fopen, SEEK_END and ftell you can determine the size of file and after SEEK_SET read the the whole file with fread.


#include <stdio.h>
#include <stdlib.h>

I'm not shore that I understood your problem.

#if 0
/* you can put here anything and the compiler wouldn't consider it */
#else
/* while this part will be considered */
#endif /* if 0 */

#include <stdio.h>
#include <string.h>

int one_less(char *);
int main()
{
char s[20];
printf("Type string\n");
scanf("%s", s);

With something like this:

if ((a[i] > '0') && (a[i] <='9'))
{
a[i] -= 1;
}

In the loop.
One remark about your code. You are not obtaining the string the right way. Read this...

You made a little mistake with your link. No big deal just test it and U will understand :)

Variable answer is float not int. Instead of printf("%d",answer); use printf("%f",answer); instead. Dont use nonstandard func (use them only if your teacher explicitly demanded). You need a getchar...

Ok while U're here just to report that the posts order are different for internet explorer and for firefox.
EDIT: is that a bug?

WHAT!?!? Okay use this

int main()
{
/* your code going here */
return 0;
}

Ah nice didn't know that it exist ([code=c]). :sad:

Um you need a main func. Where did you declared the age variable?

do
{
/* stuff */
} while(/*your code going here */);

This is a do while loop, not

do

Did you copile this? Use [ CODE] [ /CODE] tags.

Also you can do it with string.

len = sprintf(buff, "%d", num);

for (i=0; i<len; i++)
{
printf("%d\n", buff[i] - '0');
}

Where num is in your case 1567.

Declare the both globals as locals inside the main func.

int transfer_sequence (char * initial_sequence, char * fix_sequence);
int check_gene (char * fix_sequence);
int main()
{

If you using scanf than:
input: G (hit enter) X (hit enter) your output GX
If using getchar
input: GX your output GX.

#include <stdio.h>

int main()
{
int sequencetemp;

What part U dont understand? The void pointer? Well void pointer can be used if you are not shore which type will be passed to func compare.
BTW const void must be separated.

sorry I didn't read your post carefully. I asume that U must use scanf, so then U must. Ok the problem is your loop. Dont increment x every time.
Check this

for ( x = 0; x < 511; ) { /* x < 511...

For obtaining single char you can use getchar which returns int. You can read this (http://faq.cprogramming.com/cgi-bin/smartfaq.cgi?answer=1044652485&id=1043284385) and this...

This is not enoughf information. Post your code.

No it dose not exist. Replace it with

do
{
/* your code going here */
} while(a<b);

Convert cust_num to string for example with sprintf.

char buff[MAX];
sprintf(buff, "%d", cust_num);
fputs(buff, fpr);
/* and for fputc */
fputc(cust_num + '0', fpr); /* suposing that cust_num...

It means how many of size_t_Size you want to write.
fwrite(buff, sizeof(int), 4, someFile) means you want to write four ints to file.

Use code tags (http://www.daniweb.com/techtalkforums/announcement8-3.html) and don't use void main (read this (http://faq.cprogramming.com/cgi-bin/smartfaq.cgi?answer=1044841143&id=1043284376))

Change the constructor to

rectangle()
{
length = 1;
width = 1;
} //constructor sets length and width defaults to 1

or

Hm never seen that (probably becouse I'm not c++ programmer). But the book never lies. Make a test just leave the construtor and what will the copiler tell U

Yuo should run throught tutorial. You should know the diffrence from set and get. For example

float getLength(float)
{
float Len;
cout << "Enter the length: ";
cin...

And the question is?

You are not calculating the total gallons after first gallon input before while, and after finishing the prog you are substacting from total gallons -1.

Did you tried cin.ignore after cin.get(ifname, 150); ?

Why don't you use the compiler to check the code. Do you have question?

I don't think that someone will provide you the source code. Try at google. I bet that you will find something

First of all fflush(stdin);won't do the work!

Ok here it is

for (unsigned int i=0; i<name.size(); i++)
{
cout << name[i] << " binary (";
decToBin(name[i], 2);
cout << ")" << endl;

A litle of help. In your for loop you can make a temp array wich will convert the name[i] to decimal with atoi.

char tmp[2] = { 0, 0 };
tmp[0] = name[i];
answer = atoi(tmp);


Figure this out

This is illegal. What did you want with this line?

#include <iostream>
#include <cstdlib>
#include <string>
using namespace std;
void decToBin(int number, int base);
int main()
{
cout<<"Enter a string: ";
string name;
