(C) Orugallu

(A) Rajarajadeva

Answer is (A) 1190

a(a + b)³ – 3a²b(a + b) 

= a(a + b) {(a + b)² – 3ab} 

= a(a + b) {a² + b² + 2ab – 3ab} 

= a(a + b) (a² + b² – ab)

x³ + x – 3x² – 3

x³ - 3x² + x - 3

x²(x - 3) +1(x - 3)

Taking ( x – 3) common

(x - 3) (x² + 1)

Therefore x³ + x – 3x² – 3 = (x – 3) (x² + 1).

\(\frac{24a^3b^3}{-8ab}\)= \((\frac{24}{-8}a^{3-1}b^{3-1})\) = - 3a²b²[Using aⁿ÷a^m = a^n-m]

Father Gilligan seeks forgiveness from God because as a priest it is his obligation to go and give the sick man his last sacraments. But he is too tired to go. The justification he gives for his errant words is that the words were spoken by his body and not himself.

It is necessary to take the right decision at a right time because it leads to success. A wrong decision taken at a particular time can result in ruining the future.

He rode very fast, recklessly. He had failed to go when the call came and now he is rushing to reach the sick man as fast as he can.

The priest was overcome with grief at the words of the widow because he had failed to come and do his duties. The man is dead.

The function tuple (seq) converts any sequence (actually, any.iterable) into a tuple with the same items in the same order. 

For example, tuple([1, 2, 3]) yields (1, 2, 3) and tuple (‘abc’) yields (‘a’, ‘b’, ‘c’). If the argument if a tuple, it does not make a copy but returns the same object, so it is cheap to call tuple( ) when you aren’t sure that an object is already a tuple. The function list(seq) converts any sequence or iterable into a list with the same items in the same order. For example, list((1, 2, 3)) yields [1, 2, 3] and list (‘abc’) yields [‘a’, ‘b’, ‘c’j. If the argument is a list, if makes a copy just like se[:j would.

Correct Answer is : (b) Row

Ans:

ROW  Is the correct answer 

When we want to select data from more than 2 tables sql join clause is used.

CORRECT ANSWER 

(d) sql join

STRLEN( ): This function calculates the length of a string. It returns the number of characters in a string, not counting the terminating null character. Its syntax is illustrated in the following program:

void main()
{
char N[ ] = “This is a book”;
int len;
len = strlen(N);
printf (“The length of the string is %d”, len);
}

strcpy () function.

Concatenation: Concatenation means joining of two different strings to form one string. In ‘C’, streat function is used to do concatenation.

STRCAT(): This function appends or concatenates the source string at the end of the target string. For example, “Rajeev” and “Sharma” on concatenation would result in a string “Rajeev Sharma”. The length of the resulting string is strlen(dest) + strlen(src).
Example:

void main()
{
char src[ ] = “Rajeev”;
char tgt[ ] = “Sharma”;
strcat (tgt, src);
printf (“\n source string = % s”, src);
printf (“\n target string = % s”, tgt);
}

Output:

source string = Rajeev

target string = Sharma Rajeev.

Program:

#include<stdio.h>
#include<conio.h>
#include void main()
{
char str [20];
puts (“enter a string in lower case”);
gets (str);
strupr (str);
printf (“upper case = %S”, str);
}

strlen() function.

(a) Flat File

Program:

#include<stdio.h>
#include<conio.h>
void main()
{
char str[20);
char temp[20];
puts (“Enter any word”);
gets (str);
strcpy (temp, str);
strrev (str);
if (strcmp (str, temp) == 0)
{
printf (“it is a palindrome”);
}
else
{
printf (“it is not a palindrome”);
}

A dialect is a class of csv module which helps to define paramters for reading and writing csv.

(a) Line Terminator

import csv

csv.register_dialect(‘myDialect’ , delimiter ‘|’)

with open(‘c:\\pyprg\\sample4.csv’ , ‘r’) as

f: reader= csv.reader(f, dialect= ’myDialect’)

for row in reader: print(row)

F.close( )

Output 

[‘RollNo’, ‘Name’ , ‘City’]

[‘12101’ , ‘Arun’ , ‘Chennai’]

[‘12102’ , ‘Meena’ , ‘Kovai’]

[‘12103’ , ‘Ram’ , ‘Nellai’]

import csv

csv.register_dialect(‘myDialect’ ,delimiter = 7,skipinitialspace=True)

F=open(‘c:\ \pyprg\ \sample2.csv’ , ’r’)

reader= csv.reader(F, dialect= ’myDialect’)

for row in reader:

print( row)

F.close( )

OUTPUT
