Write a program to 'search' for a 'real number' in a sentence, convert it to a floating point number.
• The program must read in all of the user input (i.e. the sentence) in one character array of appropriate size. It then searches to find a real number and then convert it to a 'float' data type.
• The size of the sentence is not fixed but will not exceed 999 characters.
• The sentence will not have any decimal point or dot '.' other than within the number.
• The sentence will not have any hyphen or minus sign '-' other than at the start of the number.
• The number will not contain any space or comma.
• There is no limit to number of decimal places in the number but they will fit within the range of float.
• There will only be one number in the whole sentence.
• The user types in the sentence and presses 'Enter' at the end to mark the end of input.

For example some legal input sentence are:
The minimum distance of moon from earth is 362570 km
The best current estimate of the age of the universe is 13.75 billion years
The Amoeba proteus may reach 800 micro meter in length
The lowest temperature ever recorded on the surface of Earth is -89.2 degrees centigrade

1)
write a c program to count the num of WORDS in its input,where a WORD is defined as any continous sequence of non-whitespace character
eg
input"+++ --- hi bye 879+3"
output: "the string has 5 words"

2)
write a c program that reads in a string from the user and output the middle item of the string .stop the program if -1 is read

input "i am busy today"
output "s"

write a program in c to display as follows:

enter 1st number =1
enter last number=10

sum is 1+2+3+4+5+6+7+8+9+10 = 55.

note:
i did the program as follows:

#include
#include
void main()
{
int a=1;
int c=0;
clrscr();
while(a<=10)
{
c=c+a;
a++;
}
printf("\n the sum= ",c);
getch();
}

output is:
sum=55.
but i actually want as
sum is 1+2+3+4+5+6+7+8+9+10 = 55.

So,SACHIN,if n%10 equals 0,this means n is exactly divisable by 10.Or whatever you need.So this is also the reason why n%2 would tell you if n is odd or even.Because n%2 can only give you 0 if n is exactly divisable by 2,therefore been even,or 1 if n is not exactly divisable by 2,therefore been odd.

Exercise 1.3 : Formulation, Computation and output presentation
The Smart Cold Company currently sells 200 fridges per month at profit of R300 per fridge. The company
now spends R2000 per month on advertising and has fixed operating costs of R1000 per month that do not
depend on the volume of sales. If the company doubles the amount spent on advertising, sales will increase
by 20%. Write a program that prints, under appropriate headings, the amount spent on advertising, the
number of sales made, and the net profit. Begin with the company’s current status, and successively
double the amount spent on advertising until the net profit "goes over the hump" that is, begins to decline.
The output should include the amount up through the first time that the net profit begins to decline
