CPS125

2. /*For Lesson for-1 */
#include <stdio.h>
void main(void)
{ int day, hour, minutes;
for(day=1; day<=3; day++)
printf("Day=%2d\n", day);
for (hour=5; hour>2; hour--) {
minutes = 60 * hour;
printf("Hour = %2d, Minutes=%3d\n",hour, minutes); }

3. /*For Lesson for-2 */
#include <stdio.h>
void main(void) {
int i, j, k, m=0;
for (i=1; i<=5; i+=2) {
for (j=1; j<=4; j++)
k = i+j;
printf("i=%3d, j=%3d, k=%3d\n", i, j, k); }
m=k+i;
printf("i=%3d, j=%3d, k=%3d, m=%3d \n", i, j, k,m);

4. HOME WORK!!!!!!!!! EXTRA PRACTICE!
/*For Lesson for-3 */
#include <stdio.h>
void main(void) {
int i, isum1=0, isum2=0, N=9;
float f, x, sum1=0.0, sum2=0.0; /*What is the result if we use double type*/
x=1.0/N;
printf("x=%f\n",x);
for (i=1;i<=N;i++) {sum1 +=x; isum1+=1;}
printf("sum1=%f, isum1=%d\n",sum1, isum1);
for (f=x;f<=1.0;f+=x) {sum2+=x; isum2+=1;}
printf("sum2=%f, isum2=%d\n",sum2, isum2); }

5. Write a Program!!!!!!! TO PRINT NUMBERS FROM 1 TO 20
TO PRINT EVEN NUMBERS FROM 1 TO 20

6. /* PROGRAM # 24 */ /*TO PRINT NUMBERS FROM 1 TO 20 */
#include<stdio.h>
main( ){
int i;
int limit=20;
for(i = 1; i <= limit; i=i+1){
printf(“%d “, i); }
puts(“ STOPPPP!!!“);

7. /* PROGRAM # 25 */ /*TO PRINT EVEN NUMBERS FROM 1 TO 20 */
#include<stdio.h>
main( ){
int i;
int limit=20;
for(i= 2; i<= limit; i=i+2){
printf(“%d “, i); }
puts(“ EVEN NUMBER! “);

8. Nested if … else #include <stdio.h> int main (void) {
int wilma, a, b,c;
scanf("%d%d%d", &a,&b,&c);
if (a > b&& a>c){
wilma = (a - b*c);
printf ("%d\n", wilma);}
else
if (b>a||b>c){
wilma = (b);
printf ("%d\n", wilma); }
wilma = (a*b*c);
return (0);

9. Write a Program!!!!!!!
TO AVERAGE ODD NUMBERS FROM 1 TO 20

10. /* PROGRAM # 26 */ /*TO AVERAGE ODD NUMBERS FROM 1 TO 20 */
#include<stdio.h>
main( ){
/* Declare the variables */
int i;
float ave;
int limit=20, sum=0, count=0; /* Initialize variables */
/* Print odd numbers 1 through 20 */
for(i= 1; i< limit; i=i+2){
printf(“%d “, i);
sum+=i;
count++; }
/* Calculate average print the result */
ave=(float)sum/count;
printf(“The average is %f.\n”, ave);

11. HOME WORK!!
TO PRINT MULTIPLES OF 3 FROM 1 TO 99 IN A MATRIX FORMAT HAVING 5 COLUMNS
TO PRINT MULTIPLES OF 3 FROM 1 TO 99 IN A MATRIX FORMAT HAVING 4 COLUMNS.

12. The while Loop condition is true */ Another type of looping structure
Application: when we don't know how many times a loop is going to be repeated.
Any FOR LOOP can be re-written as a WHILE LOOP, but the other way around is not necessary true.
General Syntax:
while ( condition ){
/* BODY OF WHILE LOOP statements executed/repeated if
condition is true */ }
Explanation:
As long as the condition is true, the body of the while loop will be executed.
If the condition is false, the statement after the Body of while-loop will be executed.

13. The while statement
The while statement permits the repetition of the statements until the condition becomes false.
