Here's how to convert the Pascal code into C code:

  1. Include necessary headers and define the main function.

    C programs require the stdio.h header for input/output operations and the main function as the entry point.

    #include <stdio.h> // Required for printf and scanf functions
    
    int main() {
        // Program logic goes here
        return 0; // Indicates successful program execution
    }
    
  2. Declare variables.

    The Pascal Var m: integer; declares an integer variable m. In C, this is int m;.

    #include <stdio.h>
    
    int main() {
        int m; // Declares an integer variable 'm'
        return 0;
    }
    
  3. Translate input/output statements.

    Pascal's Writeln is equivalent to C's printf, and Readln is equivalent to C's scanf. Remember to add \n for newlines in printf and use & before the variable in scanf.

    #include <stdio.h>
    
    int main() {
        int m;
    
        printf("Type in your last score in ICT test\n"); // Equivalent to Writeln
        scanf("%d", &m); // Equivalent to Readln, %d for integer, &m for address of m
        return 0;
    }
    
  4. Convert the conditional statement.

    Pascal's If ... then ... Else ... structure translates directly to C's if (...) { ... } else { ... }.

    #include <stdio.h>
    
    int main() {
        int m;
    
        printf("Type in your last score in ICT test\n");
        scanf("%d", &m);
    
        if (m < 50) { // If condition
            printf("You have failed\n"); // Code to execute if true
        } else { // Else block
            printf("You have passed\n"); // Code to execute if false
        }
    
        return 0;
    }
    

    The final C code is:

    #include <stdio.h>
    
    int main() {
        int m;
    
        printf("Type in your last score in ICT test\n");
        scanf("%d", &m);
    
        if (m < 50) {
            printf("You have failed\n");
        } else {
            printf("You have passed\n");
        }
    
        return 0;
    }
    

    This C code will prompt the user to enter a score, then check if the score is less than 50. If it is, it prints "You have failed"; otherwise, it prints "You have passed".
