See the below c program(why the program is ending at 1 and not going upto -infinity?what is the meaning of if(--i)???

#include <stdio.h> int main() { static int i=5; if(--i){ printf("%d\n",i); main(); } } https://code.sololearn.com/cYd6UzlumKli/?ref=app

Hey Vatsav prefix (--i) decrement 1 from " i " , and any non-zero value is true value for conditional expression , so it print 5,4,3,2,1 and at 0 it becomes false so terminates !

its a prefix expression. examples: i++ i-- --i ++i the first couple, increments/decrements the variable after loop completes the second couple increments/decrements before the variable is read
