Code:#include <stdio.h> #include <stdlib.h> int primecheck(int N, int Y); void main() { int u,l,x; float z,a; while(scanf("%d %d",&u,&l)==2){ if(l>u){ u=a; l=u; a=u; } x=primecheck(u,l); z=(x/(l-u))*100; printf("%f",x); } } int primecheck(int N, int Y) { int c=0,i,k; for(i=N; i<=Y; i++){ k=(i*i)+i+41; if(k%2!=0){ c++; } } return c; }
no compilation errors. but program crashed. newbie here T_T
