CProgram This code takes a product code eg ATL1203S14 or WSF

C-Program

This code takes a product code (e.g. ATL1203S14 or WSF1357S16) and separates the code into parts:

Warehouse: ATL

Product: 1203

Qualifiers: S14

I had it working, but now the output is all messed up, can anyone see the problem?

My Code:

#include <stdio.h>
#include <string.h>
#define BUFSIZ 10
#define INPUT_SIZE 30

int main()
{
///Declare Variables
char buff[BUFSIZ], input[INPUT_SIZE];
int first, last;

///Get data string representing product code
printf(\"Enter MMOC Product Code: \");
scanf(\"%s\", input);

/*Use loop to check the first position of the digit from the given input. Initially, start
at position 0, then later, check the condition whether the first starting digit begins with any number between
0-9. Increment the value of the first until it encounters with digit.*/

///Find Position of First Digit
for(first = 0; !(input[first] >= \'0\' && input[first] <= \'9\'); ++first)

/*Copy the substring of input array value into a buff array with length first. Since, the value of first is
obtained from the loop which is mentioned in the code above. Store the ending value as \"\\0\". Then, print
the warehouse value from the given product code which is separated by using the method strncpy.*/

///Copying the string using strncpy()function

strncpy(buff, input, first);
buff[first] = \'\\0\';

///Printing Warehouse
printf(\"Warehouse: %s\ \", buff);

/*Use for loop to check the position of the product code from the given input. Initially, start the
value of last which holds the value of the first, then later, check the condition whether the input
starts with capital letter. Increment the value of last until it encounters with a capital letter.*/

///Finding First Capital Letters Following Digits
for(last = first; input[last] < \'A\' || input[last] > \'Z\'; ++last)

/*Copy the substring of input array value into a buff array with length value (last-first). Store the ending
value of buff as \"\\0\". Then, print the product value from the given product code which is separated by using
the method strncpy. Then print the qualifiers value.*/

///Copying the string using strncpy()function
strncpy(buff, &input[first], last - first);
buff[last -first] = \'\\0\';

///Printing Product and Qualifiers
printf(\"Product: %s\ \", buff);
printf(\"Qualifiers: %s\ \", &input[last]);

///Return Successfully

return 0;
}

Solution

Give it a check to the below code, it is running successfully in ideone:

#include <stdio.h>
#include <string.h>
#define BUFSIZ 10
#define INPUT_SIZE 30
int main()
{
///Declare Variables
char buff[BUFSIZ], input[INPUT_SIZE];
int first, last;
///Get data string representing product code
printf(\"Enter MMOC Product Code: \");
scanf(\"%s\", input);
/*Use loop to check the first position of the digit from the given input. Initially, start
at position 0, then later, check the condition whether the first starting digit begins with any number between
0-9. Increment the value of the first until it encounters with digit.*/
///Find Position of First Digit
for(first = 0; !(input[first] >= \'0\' && input[first] <= \'9\'); ++first)
/*Copy the substring of input array value into a buff array with length first. Since, the value of first is
obtained from the loop which is mentioned in the code above. Store the ending value as \"\\0\". Then, print
the warehouse value from the given product code which is separated by using the method strncpy.*/
///Copying the string using strncpy()function
strncpy(buff, input, first);
buff[first] = \'\\0\';
///Printing Warehouse
printf(\"Warehouse: %s\ \", buff);
/*Use for loop to check the position of the product code from the given input. Initially, start the
value of last which holds the value of the first, then later, check the condition whether the input
starts with capital letter. Increment the value of last until it encounters with a capital letter.*/
///Finding First Capital Letters Following Digits
for(last = first; input[last] < \'A\' || input[last] > \'Z\'; ++last)
/*Copy the substring of input array value into a buff array with length value (last-first). Store the ending
value of buff as \"\\0\". Then, print the product value from the given product code which is separated by using
the method strncpy. Then print the qualifiers value.*/
///Copying the string using strncpy()function
strncpy(buff, &input[first], last - first);
buff[last -first] = \'\\0\';
///Printing Product and Qualifiers
printf(\"Product: %s\ \", buff);
printf(\"Qualifiers: %s\ \", input);
///Return Successfully
return 0;
}

hope it helps.
