Thanks for the examples.
Im not being able to find out what exactly the error is here:
#include
void main()
{
int numsweet;
double cost;
printf(“How many icecream do you want : “);
scanf(“%f, &numsweet”);
cost = 12.10 * numsweet;
if (numsweet > 1000)
{
printf(“The store does not have that much icecream in stock!”);
}
else
{
printf(“You have to pay $%f to the cashier!\n Thankyou!\n”, cost);
}
}

It gives a warning saying says “Possible use of numsweet before definition in funtion main. Plz help! any advice is welcomed.

I am trying to use the following ‘awk’ command to print 60 6-column x 100 row text files to one large text file, i.e.

awk ‘{print $1, $2, $3, $4, $5, $6}’ textfile1.txt >> Batch_data_file.txt

The command works for all but four text files. For each of these four problem text files, it prints the first row of all six columns and nothing more. Why might ‘awk’ not be printing the remaining 99 rows?

Any help would be much appreciated.

awk ‘{
if ($3 ==”" || $4 == “” || $5 == “”)
print “Some score for the student”,$1,”is missing”;’
}’ student-marks

There is a extra – ‘ – at the end of line ” print “Some score for the student”,$1,”is missing”;’ ” please remove it,

Example 1 should read:

awk ‘{
if ($3 ==”" || $4 == “” || $5 == “”)
print “Some score for the student”,$1,”is missing”;
}’ student-marks

NOTE: There is an extra ” ‘ ” character in your example.
