Answer:
Increased processor speed and multi core technologies.
Explanation:
The development of processors over the years is overwhelmingly fast. The CPU use to be cumbersome, expensive and computational speed was moderate.
As it evolves, the CPU was minimized to give rise to microprocessors.
Microprocessors are very fast, running millions of processes on its core. The multiple core processors helped to increase the speed of these processors.
When there are more than one core in a processor (dual, quad or octal core), it processes data in parallel reducing the time of execution compared to a one core processor.
A company having computers with single core would need to upgrade to a new computer with multi core processor to promote speed in data processing.
Answer:
void main(){
string name;
printf("Enter Name\n");
stdin("%s",&name);
Printf("\nGreetings %s",name);
}
Explanation:
Here scanf is represented by stdin and we are using that scanner object to read the string value from user.The value which we read are printed in a new line using printf .The format specifier %s in printf is replaced by name variable
Answer:
NULL is the correct answer of this question.
Explanation:
The insert statement is used for inserting a column list into the database this statement is an under Data Manipulation language.When we insert any column into the database there is always a null value stored.
- Insert statement is used to insert the data into the database .
- To insert data following syntax is used:-
insert into tablename (column data type).
- When we insert any data into the database the default value is stored is bull.
