- FLT_EPSILON : The smallest x(float) for which 1.0+x != 1.0.
- DBL_EPSILON : The smallest x(double) for which 1.0+x != 1.0.
char* deblank(char* input)
{
char *output=input;
int j = 0;
for (int i = 0; i<strlen(input); i++,j++)
{
if (input[i]!=' ')
output[j]=input[i];
els
j--;
}
output[j]=0;
return output;
}
