How to find min and max of two (2) int numbers in C

Answer 1

#include <stdio.h> 

int min(int a, int b);
int max(int a, int b);

int main(void)
{
    printf("max = %i\n", max(3, 7)); // max = 7
    printf("max = %i\n", max(20, 8)); // max = 20
    
    printf("min = %i\n", min(4, 9)); // min = 4
    printf("min = %i\n", min(40, 13)); // min = 13
    
    return 0;
}
 
int max(int a, int b)
{
    int t = a;
       
    if (b > t) t = b;

    return t;
}

int min(int a, int b)
{
    int t = a;
       
    if (b < t) t = b;

    return t;
}   

/*
run:
 
max = 7
max = 20
min = 4
min = 13

#include <stdio.h> 

#ifndef max
	#define max(a, b) ( ((a) > (b)) ? (a) : (b) )
#endif

#ifndef min
	#define min(a, b) ( ((a) < (b)) ? (a) : (b) )
#endif

int main(void)
{
    printf("max = %i\n", max(3, 7)); // max = 7
    printf("max = %i\n", max(20, 8)); // max = 20
     
    printf("min = %i\n", min(4, 9)); // min = 4
    printf("min = %i\n", min(40, 13)); // min = 13
    
    return 0;
}
 
/*
