Explanation<\/h2>\n\n\n\n
return 0;<\/code>: This indicates that the program has executed successfully and is returning an exit status of 0<\/code>.<\/p>\n\n\n\n
#include <stdio.h><\/code><\/strong>:<\/p>\n\n\n\n
This line includes the standard input-output library. It allows us to use functions like printf<\/code> for output and scanf<\/code> for input.<\/p>\n\n\n\n
int main()<\/code><\/strong>:<\/p>\n\n\n\n
This defines the main function where the program starts executing. The int<\/code> indicates that this function will return an integer.<\/p>\n\n\n\n
Variable Declaration<\/strong>:<\/p>\n\n\n\n
int num1, num2;<\/code>: Here, we declare two integer variables, num1<\/code> and num2<\/code>, to store the numbers that the user will input.<\/p>\n\n\n\n
Input from the User<\/strong>:<\/p>\n\n\n\n
printf(\"Enter the first number: \");<\/code>: This prompts the user to enter the first number.<\/p>\n\n\n\n
scanf(\"%d\", &num1);<\/code>: This reads the integer input from the user and stores it in num1<\/code>. The &<\/code> operator is used to refer to the address of num1<\/code>.<\/p>\n\n\n\n
The same steps are repeated to get the second number, storing it in num2<\/code>.<\/p>\n\n\n\n
Finding the Maximum<\/strong>:<\/p>\n\n\n\n
The program uses an if<\/code> statement to compare the two numbers:<\/p>\n\n\n\n
if (num1 > num2)<\/code>: If num1<\/code> is greater than num2<\/code>, it prints that num1<\/code> is the maximum.<\/p>\n\n\n\n
else if (num2 > num1)<\/code>: If num2<\/code> is greater than num1<\/code>, it prints that num2<\/code> is the maximum.<\/p>\n\n\n\n
else<\/code>: If neither condition is true, it means both numbers are equal, and it prints that they are equal.<\/p>\n\n\n\n
Return Statement<\/strong>:<\/p>\n\n\n\n
return 0;<\/code>: This indicates that the program has executed successfully and is returning an exit status of 0<\/code>.<\/p>\n\n\n\n
OUTPUT<\/h2>\n\n\n\n
Enter the first number: 15
Enter the second number: 10
The maximum of 15 and 10 is 15<\/p>\n\n\n\n
Enter the first number: 7
Enter the second number: 7
Both numbers are equal: 7<\/p>\n\n\n\n
