Hi,
I don't find the way to check if the input I give to the function scanf is
an int or a char. For example you ask to enter an int, and if a char is
entered -> BUG, so I need something to check if tne input is an int.
It's easy to check if it's a char, but int .... I didn't find.
I wrote this function but it doesnt work, can you help me .....
int input_one_int(char CHAINEval[],int MAXval,int MINval)// Rmq: Bug if char
entered
{
int test=0,check=0,value;
do
{
printf("\r%s : ",CHAINEval);
fflush(stdout);
fflush(stdin);
test=scanf("%d*[^\n]",&value);
if (test==EOF)
{
printf("syntax error");
}
if ((value<=MAXval)&&(value>=MINval)) check=1;
} while ((test!=1)||(check==0));
return value;
thank for any help ...
}
