Swap 2 variable without a 3rd variable in c program?

This can be done using the bitwise exclusive-or(XOR) operator. int X = 16 // Binary 010000 int Y = 32 // Binary 100000 X = X ^ Y // X = 110000 Y = X ^ Y // Y = 010000 X = X ^ Y // X = 100000 This is good to know but is not widely practiced, as it is far simpler to use a temporary variable, and less prone to bugs. int temp = X; X = Y; Y = temp;


What is the password for Level 10-8 on the Starfy Nintendo game?

Simple... THERE ISN'T ONE! The numbers on the door represent the time you must get in each level to open the door. For example (This is only an example and is not the actual number I would believe): 10-1 010000 would mean you have to complete level 10-1 in under 1 minute. Colon are placed in correct spots to help: 01:00:00. See the relativity?


How many centimeters are in decameters?

AnswerI believe you are asking how many centimeters are in a decameter.The simple answer is 1000.Kilo Hecto Deca Meter Deci Centi Milli.010000 0.1000 1.0000 10.000 100.00 1000.0 10000You simply move the decimal point 4 places to the right. You have 1 decameter or in the illustration above 1.0000 decameters. Centimeter is 4 places to the right of decameter so move the decimal point the many places and you have 1000.0 centimeters.

How can you rewrite a perfect square as a exponent?

Find its square root and raise it in the second power.64 = 8281 = 92841 = ?2 you need to work a little bit here1. base would be in two digits (odd number with 3 digits, (3+1)/2)2. the first digit would be 2 (the square of 2 is less than 8), so the base would be between 20 and 30.3. the second digit would be 9 (the square of 9 ends in 1)4. the answer is 29, 841 = 292529 = ?21. base would be in two digits (odd number with 3 digits, (3+1)/2)2. the first digit would be 2 (the square of 2 is less than 5), so the base would be between 20 and 30.3. the second digit would be 3 or 7 (the square of 3 and 7 end in 9); is it 23 or 27?4. 529 - 2232 = 529 - 409 = 120; it is 3, because 2(2*3)=12. So 529 = 2322809 = ?21. base would be in two digits (even number with 4 digits, 4/2)2. the first digit would be 5 (the square of 5 is less than 28,), so the base would be between 50 and 60.3. the second digit would be 3 or 7 (the square of 3 and 7 end in 9); is it 53 or 57?4. 2809 - 5232 = 2809 - 2509 = 300; it is 3, because 2(5*3)=30. So 2809 = 5327056 = ?21. base would be in two digits (even number with 4 digits, 4/2)2. the first digit would be 8 (the square of 8 is less than 70,), so the base would be between 80 and 90.3. the second digit would be 4 or 6 (the square of 4 and 6 end in 6); is it 84 or 86?4. 7056 - 8242 = 7056 - 6416 = 640; it is 4, because 2(8*4)=64. So 7056 = 8427396 = ?21. base would be in two digits (even number with 4 digits, 4/2)2. the first digit would be 8 (the square of 8 is less than 73), so the base would be between 80 and 90.3. the second digit would be 4 or 6 (the square of 4 and 6 end in 6); is it 84 or 86?4. 7396 - 8262 = 7396 - 6436 = 960; it is 6, because 2(8*6)=96. So 7396(if you test 4 first, you'll see that it doesn't work, so it will be 6)55696 = ?21. base would be in three digits (odd number with 5 digits, (5+1)/2)2. the first digit would be 2 (the square of 2 is less than 5), so the base would be between 200 and 300.3. the last digit would be 4 or 6 (the square of 4 and 6 end in 6); is it 2_4 or 2_6?4. let's work a little bit here:2_4; 22_42 = 4001640016+ ... = 4569600080 (101*2*4*_, we need to find the middle digit)01600 (102*2*2*4)04000 (103*2*2*_)55696 - 45696 = 10000400160008001600040001000000080 doesn't change, this tell us the middle digit can be 1 or 6. But one is too small and 6 is too big (2*2*1= 4, 2*2*6=32). So the last digit is not 4, it is 6. Let's find the middle digit.2_6; 22_62 = 4003640036+ ... = 4655600120 (101*2*6*_, we need to find the middle digit)02400 (102*2*2*6)04000 (103*2*2*_)55696 - 46556 = 9140400360012002400040000914000120 becomes 00160, and tell us the middle digit can be 3 or 8, but 8 is too big (2*2*8=32), so it is 3Thus, 55696 = 2362.263169 = ?21. base would be in three digits (even number with 6 digits, 6/2)2. the first digit would be 5 (the square of 5 is less than 26), so the base would be between 500 and 600.3. the second digit would be 3 or 7 (the square of 3 and 7 end in 9); is it 5_3 or 5_7?4. let's work a little bit here:5_3; 52_32 = 250009250009+ ... = 263069000060 (101*2*3*_, we need to find the middle digit)003000 (102*2*5*3)010000 (103*2*5*_)263169 - 263069 = 10025000900006000300001000000010000060 doesn't change so the only possibility is when the middle digit is 1.Thus, 2631169 = 5132
