Solution of Codeforces Round #244 (Div. 2) - Police Recruits in C.

The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom.” ― Isaac Asimov Again, I found this problem at http://codeforces.com/contest/427/problem/A . Here is the solution:- #include <stdio.h> #include <stdlib.h> int main(){ long police=0,unNoticedCrime=0,n,i; int x; fscanf(stdin,"%ld",&n); if(n>=1 && n<=100000){ for(i=0;i<n;i++){ fscanf(stdin,"%d",&x); switch (x){ case -1: if(police > 0) --police; else ++unNoticedCrime; break; default: police+=x; } } } fprintf(stdout,"%ld",unNoticeCrime); return(0); }

C program to express number into words.

There is an UNEQUAL amount of good and bad in most things, the trick is to work out the ratio and act accordingly - The Jester This is a program to express number into words. Examples: Input : 123 Output: One Hundred Twenty Three Input 123456 Output : One Hundred Twenty Three Thousand Four Hundred Fifty Six This post is divided into following parts. Expressing two digit number in words. Expressing three digit number in words. Expressing number in words. All code at once. Note : This program was compiled on DEV C++ Expressing Two Digit Number In Words :- Here is the code: char *tens(int n){ int a; char *p,temp[20]; char t1[][10]={"Zero","One","Two","Three","Four","Five","Six","Seven","Eight","Nine","Ten", "Eleven","Twelve","Thirteen","Fourteen","Fifteen","Sixteen...

Difference between pre-increment and post-increment operator in C.

If you're not part of the solution, you're part of the precipitate. -Henry J. Tillman Greetings, today we are going to find out the difference between the pre-increment(++a) and post-increment(a++) operator in C- as the title says. The best way to learn anything is by example, so here it is, Example 1:-  //Pre-increment operator #include <stdio.h> int main(void) { int a=3; printf("%d",++a); return 0; } Output: 4 //Post-increment #include <stdio.h> int main(void) { int a=3; printf("%d",a++); return 0; } Output: 3 Explanation: As you can see there is difference in the output. The printf("%d",a++) is composed of two statements: printf("%d",a); a=a+1; In pre-increment,  a=a+1 ; is evaluated before printf("%d,"a); In post-increment,  printf ("%d",a); is evaluated  before a=a+1;
