#include <stdio.h>
void permute ( char* strptr, int start, int length )
{
int count1;
int count2;
int temp;
for ( count1 = start; count1 < length - 1;
++count1 ) {
for ( count2 = count1 + 1; count2 < length;
++count2 ) {
temp = strptr [ count1 ]; strptr [
count1 ] = strptr [ count2 ]; strptr [ count2 ] = temp;
permute ( strptr, count1 + 1,
length );
temp = strptr [ count1 ]; strptr [
count1 ] = strptr [ count2 ]; strptr [ count2 ] = temp;
}
}
printf ( "\n%s", strptr );
}
int main ( int argc, char* argv [] )
{
char str[] = "abcd";
permute ( str, 0, ( strlen ( str ) ) );

What are global variables?
In this assignment you are asked to write a multithreaded program to find the duplicates in an array of 10 million integers. The integers are between -5000,000 to 5000,000 and are generated randomly. Use 10 threads, each thread works on 1000,000 integers. Compare the time needed to accomplish the task with single thread of execution program. Do not include the time to fill the array with integers in the execution time.
write a program to generate address labels using structures?
Given only putchar (no sprintf, itoa, etc.) write a routine putlong that prints out an unsigned long in decimal. [ I gave the obvious solution of taking % 10 and / 10, which gives us the decimal value in reverse order. This requires an array since we need to print it out in the correct order. The interviewer wasn't too pleased and asked me to give a solution which didn't need the array ].
