Decoding

this function should find out the first element of array is an interger or a character, then store that element to character named C. but it does not do that..
What can be wrong?

this is my input function

Code:

gets(userinput);
decodeinput(userinput);

here's decoding function

Code:

void decodeinput(char input[100])
{

int i;
char input3[100];

for(i=0; i<100; i++)
input3[i] = input[i];

strupr(input3); /* Make command to upper case */
if('0' < input[0]  <'9')
num = input[0];
else if ('A' < input3[0] < 'Z')
{   
	c = input3[0];
    printf("%c", c);
    num = 0;
}

There are a lot of problems with the code

Two of the problems are

1) the if condition should be

if('0' < input[0] && input[0] <'9')

2) if you put a char into an int , like int x = '6', the value 6 will not be put in the int , instead the ASCII value will be put in

for example

int i = '2';
cout << i;

prints 50

Code:

for(i=0; i<100; i++)
input3[i] = input[i];

use strcpy() to copy input to input3

syntax : strcpy(input3,input);

I couldn't agree more. The first problem however, is with the very first line. I'll paste it in here, you see if you can spot it:

gets(userinput);

Quzah.

Code:

char userinput[100];

gets(userinput);

if gets(userinput) is wrong, then which function should I use?
scanf?
getch?
