Create a new text file and enter the following C code:

                #include <stdio.h>

                int main() {
                    int a, b, c, max;
                    printf("Enter three integers: ");
                    scanf("%d %d %d", &a, &b, &c);

                    max = a;
                    if (b > max) max = b;
                    if (c > max) max = c;

                    printf("Maximum: %d", max);

                    return 0;
                }
            

This program takes three integers as input and prints the maximum value.

Use your C compiler to compile the code. For GCC, you can use the following command in the terminal:

gcc -o maxProgram yourProgram.c

Replace "yourProgram.c" with the name of your file.

After compiling the code, run the executable:

./maxProgram

Follow the on-screen prompts to enter three integers and see the maximum displayed.
