Program:

#include <stdio.h>

int main(void) 
{
	unsigned int value;

	printf("Enter an unsigned int value: ");
	scanf("%u", &value);
	printf("value: %u\n", value);

	//input again 
	printf("Enter an unsigned int value again: ");
	scanf("%u", &value);
	printf("value: %u\n", value);

	//input again
	printf("Enter an unsigned int value again: ");
	scanf("%u", &value);
	printf("value: %u\n", value);

	return 0;
}

Output

Enter an unsigned int value: 123712
value: 123712
Enter an unsigned int value again: -1
value: 4294967295
Enter an unsigned int value again: 25501
value: 25501

Note: See the input second and its result, when we provide -1 to an unsigned integer value, it assigns "maximum value to an unsigned int" to the variable.
