2 שאלה num 1>num 2>num 3 : נניח שאנו רוצים לקבל num 1 ? num 2 num 1 ? num 3 num 2 ? num 3 : מצב התחלתי num 1 > num 2 num 1 ? num 3 num 2 ? num 3 num 1 > num 2 num 1 > num 3 num 2 > num 3 : מצב סופי

2 שאלה #include <stdio. h> int main() { int num 1, num 2, num 3; //These are the numbers that will be sorted. int temp; //This is a variable that will be used for swapping. printf("Please enter three integers: n"); scanf("%d %d %d", &num 1 , &num 2 , &num 3); if(num 1 < num 2) { //Swap between num 1 and num 2 so that num 1 will //hold the larger value: temp=num 1; num 1 > num 2 num 1=num 2; num 1 ? num 3 num 2=temp; num 2 ? num 3 }

2 שאלה } if(num 1 < num 3) { //Swap between num 1 and num 3 so that num 1 will hold the //larger value: num 1 > num 2 num 1 > num 3 temp=num 1; num 2 ? num 3 num 1=num 3; num 3=temp; } if(num 2 < num 3) { //Swap between num 2 and num 3 so that num 2 will hold the //larger value: num 1 > num 2 num 1 > num 3 temp=num 2; num 2 > num 3 num 2=num 3; num 3=temp; } printf("The numbers in increasing order are: %d, %d and %d. n", num 3, num 2, num 1);
