c - Why value of a variable of int type gets printed even if it does not lie in the range of int? -

#include<stdio.h> int main() { int a; a=100000000; printf("%d",a); return(0); } 

//why value of gets printed if larger range of int?

because range of int type in c -32767 32767

you have false assumptions there.

the range of type int not fixed. int not 16 bits.

the c standard doesn't define fixed range int. requires conforming implementation supports at least range -32767 32767 int. implementation can support higher ranges. on systems, int 32 bits wide.

so there's nothing unexpected in output. if want know exact limits can use macros int_min , int_max <limits.h>.
