...*Q:-1 Write Essay on the American Revolution*
The American Revolution was a monumental event in world history that took place between 1775 and 1783, resulting in the thirteen American colonies breaking away from British rule and establishing the United States of America. This revolution was not just a war for independence but a profound transformation in political philosophy, national identity, and global influence.

...Q1. Discuss the key features of modernist fiction. How do they differ from traditional narrative forms?
Modernist fiction, which emerged in the late 19th and early 20th centuries, marks a radical departure from the conventions of traditional narrative forms. It arose as a response to the disruptions of the modern world—such as industrialization, urbanization, war, and shifting philosophies—which challenged established beliefs and modes of representation. Traditional narratives, especially in
1. Different between raster and vector graphics method. what do you prefer
=>Raster: *//it Representation Pixels *//Resolution-dependent *//Larger (esp. high-res images) *//Blurs/pixelates on scaling *//JPG, PNG, BMP
=.>VectorG : *//Mathematical formulas (lines, curves) **//Resolution-independent *//Smaller *//Scales cleanly *//SVG, EPS
If working with photos or detailed images: Raster is better. If designing logos, icons, or anything that needs to scale (e.g., for both mobile and billboard)
//prime
int num, i, isPrime = 1;//after this print and scan num
if (num <= 1) {
isPrime = 0;
} else {
for (i = 2; i <= num / 2; i++) {
if (num % i == 0) {
isPrime = 0;
break; }}}
if (isPrime)
printf("%d is a prime number.\n", num);
else{print no prime}

What is Big Data
Data which are very large in size is called Big Data. Normally we work on data of size MB (WordDoc ,Excel) or maximum GB(Movies, Codes) but data in Peta bytes i.e. 10^15 byte size is called Big Data. It is stated that almost 90% of today's data has been generated in the past 3 years.
Sources of Big Data
These data come from many sources like
Social networking sites: Facebook, Google, LinkedIn all these sites generates huge amount of data on a day to day basis as they have...
