Problem Statement
Cast the float value 9.7 to a float in different ways: implicit, explicit, using floor, using cel. What will be the result in each case and why?
Input Format
A float value: 9.7
Output Format
Result of conversion using:
• implicit cast
• explicit cast
• floor()
• ceil()
• implicit cast
• explicit cast
• floor()
• ceil()
Example
9.7
Implicit cast : 9 Explicit cast : 9 floor(9.7) : 9 ceil(9.7) : 10
Constraints
• Floating point value
• Conversion to integer result
• Conversion to integer result
Concept Explanation
Different methods convert 9.7 to an integer in different ways.
Step-by-Step Explanation
1. Implicit casting
• Float is automatically converted to int.
• Decimal part is discarded.
• Result: 9
2. Explicit casting
• Manually convert using (int)9.7.
• Decimal part is discarded.
• Result: 9
3. floor()
• Returns the largest integer less than or equal to the value.
• floor(9.7) → 9
4. ceil()
• Returns the smallest integer greater than or equal to the value.
• ceil(9.7) → 10
• Float is automatically converted to int.
• Decimal part is discarded.
• Result: 9
2. Explicit casting
• Manually convert using (int)9.7.
• Decimal part is discarded.
• Result: 9
3. floor()
• Returns the largest integer less than or equal to the value.
• floor(9.7) → 9
4. ceil()
• Returns the smallest integer greater than or equal to the value.
• ceil(9.7) → 10

Example Solution (Public)
#include <stdio.h>
#include <math.h>
int main() {
float a = 9.7;
int x, y, z, w;
/* Implicit casting */
x = a;
/* Explicit casting */
y = (int)a;
/* Using floor() */
z = floor(a);
/* Using ceil() */
w = ceil(a);
printf("Original value: %.2fnn", a);
printf("Implicit casting result = %dn", x);
printf("Explicit casting result = %dn", y);
printf("Using floor() result = %dn", z);
printf("Using ceil() result = %dn", w);
return 0;
}
