program in C launches correctly but printf doesnt show anything -

i run programm , console appears printf doesnt print anything, how can fix this?

#include<stdio.h> main() {     float fa;     int cel;     cel=0;     while(cel<=200);     {         fa=9.000*(cel+32.000)/5.000;         printf("%d\t%.3f\n",cel,fa);         cel=cel+20;     } } 

in addition have similar program runs correctly

#include<stdio.h> main() {   float celsius;   int fahr;   fahr = 0;     while(fahr<=100){     celsius=5.0000*(fahr-32.0000)/9.0000;     printf("%d\t%.4f\n",fahr,celsius);     fahr=fahr+1;   } } 

i ran both programs in c-free 5

infinite loop:

while(cel<=200); 

because of trailing ; equivalent to:

while(cel<=200) {} 

which means printf() never reached , cel never modified. remove ; correct.
