Lab Sheet # 2

Write the following program in the Visual C++ editor. Compile and run the program and observe the output.

#include <stdio.h>

int main()
{
    int luckyNumber = 5;
    float radius = 2;
    char myName[15] = "John";
    char initial = 'J';

    printf("Hello World\n");    /* The format string contains only ordinary
                    characters. */

    printf("My lucky number is %d\n", luckyNumber);    /* The "%d" specifies
                   that an integer value will be output. */

    printf("My name is %s\n",myName);    /* The %s specifies that a character
            string will be output. */

    printf("My first initial is %c\n",initial);    /* The %c specifies that a
                   character will be output. */

    printf("The radius of the circle %f\n", radius);
                   /* %f specifies that a float will be output. */

    printf("Hello %s or should I say %c\n",myName,initial);
                   /* Multiple arguments of different types may be output. */

return(0);
}

Write the following program in the Visual C++ editor. Compile and run the program and observe the output

/* A program to add two integer numbers */

#include <stdio.h>

int main()

{

char yourName[15]; /* declaration */

int integ1, integ2, sum;

printf("Enter your name: ");
scanf("%s",yourName); /* yourName is a character array */
printf("Hello %s\n",yourName);

printf(“Enter 1st integer\n”); /* prompt */

scanf(“%d”,&integ1); /* read an integer */

printf(“Enter 2nd integer\n”); /* prompt */

scanf(“%d”,&integ2); /* read an integer */

sum=integ1+integ2; /* assignment of sum */

printf(“Sum is %d\n”,sum); /* print sum */

return 0;

}

Sample input:

Enter 1st integer

Enter 2nd integer

Sample output:

Sum is 117

Problem 1: Write a program that will calculate the average of four integer numbers.

Sample Input:

Enter 1st Integer: 4

Enter 2nd Integer: 6

Enter 3rd Integer: 3

Enter 4th Integer: 7

Sample Output:

Average of 4, 6, 3 and 7 is 5
