Answer:
input.open("rawdata");
input>>datum;
input.close();
Explanation:
ifstream objects maintain a filebuf object as their internal stream buffer, and perform operations like input/output on the available associated files.
In above statements.
input.open("rawdata");
- The associated file named rawdata is opened.
input>>datum;
- The integer from the file is read into already declared variable datum.
input.close();
Answer:
In Python:
N = int(input("Positive integer: "))
if N > 0:
flag = False
for i in range(1,N+1):
if i * i == N:
flag = True
break
print(str(flag))
else:
print("Positive integer only")
Explanation:
N = int(input("Positive integer: "))
If the number is positive
if N > 0:
This initializes a boolean variable to false
flag = False
This iterates from 1 to the input integer
for i in range(1,N+1):
This checks if th number is a square of some integer
if i * i == N:
If yes, flag is set to true
flag = True
The loop is exited
break
This prints either true or false, depending on the result of the loop
print(str(flag))
If otherwise, that the number is not positive
<em>else:</em>
<em> print("Positive integer only")</em>
