Please HELP!!!
Can anybody tell me what's wrong with this?
When I test the program it works fine.
I end the input using ctrl-D , Is that wrong?
#include<stdio.h>
#include<math.h>
#include<string.h>
#include<stdlib.h>
/*function to reverse a string*/
void strrev(char string[256])
{
char reverse[256];
int i,j;
i=strlen(string);
for (j=i-1;j>=0;j--)
{
reverse[i-1-j]=string[j];
}
reverse[i]='\0';
strcpy(string,reverse);
}
int main(void)
{
int k=0,i=0,j,different=0,start=0;
int c;
char stream[256];
char num[256];
char copy[256];
double number;
while((c=getchar())!=EOF)
{
stream[i]=c;
j=i;
i++;
}
for (k=j;k>=0;k--)
{
if(isdigit(stream[k])!=0)
{
if(isdigit(stream[k-1])!=0)
{
num[start]=stream[k];
start++;
}
else
{
num[start]=stream[k];
num[start+1]='\0';
// printf("%s\n",num);
strrev(num);
// printf("%s\n",num);
strcpy(copy,num);
number=strtod(copy,NULL);
printf("%0.4f\n",sqrt(number));
start=0;
}
}
}
return 0;
}
