Thread: Issues with Binary conversion program

I'm having issues linking the main program to the function program/file. Not sure whats causing the error. This is the first time I'm linking to programs together. Also I'm having a issue designing a function to convert a "float int" into binary. Any help would be appreciated.

Thank you,
Robert Brown

// Write a small main program (driver) to test your functions.

//
// 1) A function called printChar that takes a character (char) argument. 
//    The function should print the binary representation of the character 
//    argument. 
// 2) A function called printShort that takes a short integer (short) argument. 
//    The function should print the binary representation of the short argument. 
// 3) A function called printFloat that takes a single-precision floating-point 
//    float) argument. The function should print the binary representation of 
//    the float argument.

// Function to convert a character into binary 
char *printChar (unsigned char c)
{
	static char bin[CHAR_BIT + 1] = {0};
	int i;
	for(i=CHAR_BIT - 1;i >= 0;i--)
	{
		bin[i]=(c%2) +'0';		
		c /= 2;		
	}
	return bin;

}     

// Function to convert a short integer into binary 
int *printShort (int number) 
{
	int remainder;

	if(number <= 1) 
    {
		cout << number;
		return;
	}

	printShort(number >> 1);

// Function to convert a float integer into binary 
float *printFloat (int)

Why don't you mention exactly what issues you are having. Regarding the conversion of a float to binary, how do you want to present this? In two's complement?

You may want to post this in the C++ forum, since it's not C.

Not sure if the one I input'ed will work right. The output for the float should look like this:

******
Enter a float: 1.115

The binary representation for 1.115 is: 0011 1111 1000 1110 1011 1000 0101 0010
******

Here is function I was trying to make.

Code:

// Function to convert a float integer into binary 
float *printFloat (int)
{    
     int n,bin[100],i,j;    
     printf("Enter your choice: \n");    
     scanf("%d",&n);    
     printf("The Binary representation for %d is: \t",n);    
     for(i=0;n!=0;i++)    
     {        
              bin[i]=n%2;        
              n=n/2;    
     }    
     for(j=i-1;j>=0;j--)    
     {        
              printf("%d",bin[j]);    
     }    
     printf("\n");
}
