Question 2 write a programme that will count from -50 to +10 and display the result 30/June/2014

 **********************Solution**************************

/*

This programme count from -50 to +10 and display the result, using for loop statement.

*/

/* include the standard input/output function */

#include <stdio.h>

/* calls the main function */

int main()

{    //  Here the programme (main function) begin

/* begin variable declared, it marks the beginning of

the number */

int begin;

/* declaration of the end variable, it marks the end of the number(10) */

int end = 10;

/* By using for loop Start count from begin (-50); due check when begin is less than or

equal  to end(10); due increase begin by 1 each time something happen OK */

for (begin = -50; begin <= end; begin++)

/* Open the for loop chunk/block of code */

{

    /* Display the value of begin each time */

    printf("%d\n", begin);

   

/* ends/close the for loop chunk/block of code */

}

    /* Pause for the user to see the result/display */

    system("PAUSE");

   

    /* The main function is not going to return any value */

    return 0;

   

/* ends/closes the main function */

Question 1 Write a C programme that will request for student score afterwards the programme will remark the student in respect to the entered scores with any of the following Letter Grades; A, B, C, D, E or F, and Display it to the user?

/*
This is a programme that request for students score afterwards the programme will remark the student with a letter grade (A, B, C, D, E or F) for each of the courses ofered by  that student
*/
This is the code/programme

#include <stdio.h>

    int score;
   
   
    /* we use count variable to count number of time we have done a particular thing or to keep track of a particular process */
    int count;
   
    /* This tells the student what enter but in a NewLine */
    printf("\nEnter the number of courses: ");
   
    /* This retrieve the entered value and keep it in the memory loaction called ncrs */
    scanf("%d", &ncrs);
   
       
    for ( count = 1; count <= ncrs; count++)

        if ( score < 0 || score > 100 )

                        or does not fall within range,");
            printf(" Please try again\n\n");

            dont follow any other instruction(stop executing */
                        break;
        }
   
        if( score >= 70 )
        {
            printf("You got an 'A' in this course!!! \n");
        }
