C Tutorial/printf scanf/scanf unsigned

o: Used for unsigned int expected"s value.

It should be an integer in octal form.

<source lang="cpp">#include <stdio.h> main() {

   int i = 0;
   int k;
   printf("an integer:");
   i=scanf("%o",&k);
   printf("total values inputted %d\n",i);
   printf("The input values %o\n",k);

}</source>

an integer:2
      total values inputted 1
      The input values 2

U: Unsigned integer in decimal form.

<source lang="cpp">#include <stdio.h> main() {

   int i = 0;
   int k;
   printf("integer:");
   i=scanf("%u",&k);
   printf("total values inputted %d\n",i);
   printf("The input values %u\n",k);

}</source>

integer:3
      total values inputted 1
      The input values 3

X: Unsigned integer in hexadecimal form.

<source lang="cpp">#include <stdio.h> main() {

   int i = 0;
   int k;
   printf("integer:");
   i=scanf("%X",&k);
   printf("total values inputted %d\n",i);
   printf("The input values %X\n",k);

}</source>

integer:2
