Trying to do underflow and overflow in C language for the integer Type.

overflow.c

#include <stdio.h>
#include <limits.h>

int main(){

	int maxValue = INT_MAX;
	int minValue =  INT_MIN;

	int overflow = 0;
	int underflow = 0;

	printf("\nMin INT %d \n", minValue);
	underflow = minValue - 1;
	printf("Underflow is %d \n ", underflow);


	printf("\nMax INT %d\n", maxValue);
	overflow = maxValue + 1;
	printf("Overflow INT %d \n ", overflow);

	return 0;
}
