### Explanation

• In the program
 int i; Define the integer variable i for (i = 1; i <= 4, i ++) Check the for loop switch (i){case 1: printf ( “% d” , i) ;break; In the for loop i = 1 than check case 1 and printf prints the value of i = 1 case 2: printf ( “% d” , i) ;break; In the for loop i = 2 than check case 2 and printf prints the value of i = 2 case 3: printf ( “% d” , i) ;break; In the for loop i = 3 than check case 3 and printf prints the value of i = 3 case 4: printf ( “% d” , i) ;break; In the for loop i = 1 than check case 4 and printf prints the value of i = 4

2. `{`
3. `    int i;`
4. `    printf ( “%d” scanf( “%d” &i) );//value 10 is given as input here`
5. `}`

### Explanation

• In a program int i; Define integer variable i printf ( “% d” scanf ( “% d” &i) ) ; //value 10 is given as input here Here scanf returns number of items successfully read and not 10.Here 10 is given as input.This should have been scanned successfully.So, number of items read is 1.
• So. The answer is 1.
