I have written one funtion like
#include <stdio.h>
seq(num)
int num;
{
int i,sum;
for (i=1; i<=num;i++)
sum+=i;
return(sum);
}
this seq funtion should have return values to unix script.

Hello friends,
I want to run this code on every document in every sub-directory.
tr -d '\n' < MulitpleInput.txt | awk '{gsub(/\. /,".\n");print}' | grep “\
I tried several looping techniques but couldn't get it to run in this example. Any ideas?
Thank you (2 Replies)
Not sure if this is possible, but I've tried this about a thousand ways now. I am making something with a lot of arrays. I thought I could put the array names into a separate array and then loop through them to call all of their elements. This is the best I've got so far:

round
ROUND(3) 1 ROUND(3)round - Rounds a floatSYNOPSIS
float round (float $val, [int $precision], [int $mode = PHP_ROUND_HALF_UP])
DESCRIPTION
Returns the rounded value of $val to specified $precision (number of digits after the decimal point). $precision can also be negative or
zero (default).
Note
PHP doesn't handle strings like "12,300.2" correctly by default. See converting from strings.
PARAMETERS
o $val
- The value to round
o $precision
- The optional number of decimal digits to round to.
o $mode
- Use one of the following constants to specify the mode in which rounding occurs.
+--------------------+---------------------------------------------------+
| Constant | |
| | |
| | Description |
| | |
+--------------------+---------------------------------------------------+
| | |
| PHP_ROUND_HALF_UP | |
| | |
| | Round $val up to $precision decimal places away |
| | from zero, when it is half way there. Making 1.5 |
| | into 2 and -1.5 into -2. |
| | |
| | |
|PHP_ROUND_HALF_DOWN | |
| | |
| | Round $val down to $precision decimal places |
| | towards zero, when it is half way there. Making |
| | 1.5 into 1 and -1.5 into -1. |
| | |
| | |
|PHP_ROUND_HALF_EVEN | |
| | |
| | Round $val to $precision decimal places towards |
| | the next even value. |
| | |
| | |
|PHP_ROUND_HALF_ODD | |
| | |
| | Round $val to $precision decimal places towards |
| | the next odd value. |
