The Program in C that computes the natural logarithm of a given number is given below:
#include <math.h>
#include <stdio.h>
int main() {
double num, result;
printf("Enter a number: ");
scanf("%lf", &num);
result = log(num);
printf("The natural logarithm of %lf is %lf", num, result);
return 0;
}
Output:
Enter a number: 12
The natural logarithm of 12.000000 is 2.484907
Pro-Tips💡
This program prompts the user to enter a number, reads the value entered by the user and stores it in the variable “num”,
then calculates the natural logarithm of “num” using the log() function from the math.h library and stores the result in the variable “result”. Finally, it prints the result to the console.
