the factorial of non-negative integer n is written n! and is defined as follows: n!=n*(n-1)*(n-2)........1(for values of n greater than or equal to 1 and n!=1(for n=0) Perform the following 1.write a c program that reads a non-negative integer and computes and prints its factorial. 2. write a C program that estimates the value of the mathematical constant e by using the formula: e=1+1/!+1/2!+1/3!+.... 3. write a c program the computes the value ex by using the formula ex=1+x/1!+xsquare/2!+xcube/3!+....

Ignou,

write a program that reads lines(using getline), converts each line to an integer using atoi, and computes the average of all the numbers read. also compute the standard deviation.

HOW TO FIND OUT THE RREVERS OF A GIVEN DIGIT NUMBER IF IT IS INPUT THROUGH THE KEYBORD BY USING C LANGUAGE

Wipro,

how to find out the reverse number of a digit if it is input through the keyboard?

atoi, which takes a string and converts it to an integer. write a program that reads lines(using getline), converts each line to an integer using atoi and computes the average of all the numbers read. also compute the standard deviation

write the function int countchtr(char string[],int ch);which returns the number of timesthe character ch appears in the string. for example the call countchtr("she lives in Newyork",'e') would return 3.

a number whose only prime factors are 2,3,5, and 7 is call humble number,,write a program to find and display the nth element in this sequence.. sample input : 2,3,4,11,12,13, and 100.. sample output : the 2nd humble number is 2,the 3rd humble number is 3,the 4th humble number is ,the 11th humble number is 12, the 12th humble number is 14, the 13th humble number is 15, the 100th humble number is 450.

a number is perfect if it is equal to the sum of its proper divisor.. 6 is perfect number coz its proper divisors are 1,2 and three.. and 1+2+3=6... a number is deficient if the sum of its proper divisor is less than the number.. sample: 8 is deficient, coz its proper divisors are 1,2 and 4, and 1+2+4=7. abundant number, if the sum of its proper divisor is greater than the number.. sample..12 is abundant coz 1+2+3+4+6=16 which is geater than 12. now write a program that prompts the user for a number, then determines whether the number is perfect,deficient and abundant..

the number 138 is called well ordered number because the three digits in the number (1,3,8) increase from left to right (1<3<8). the number 365 is not well ordered coz 6 is larger than 5. write a program that wull find and display all possible three digit well ordered numbers. sample: 123,124,125,126,127,128,129,134 ,135,136,137,138,139,145,146,147 148 149,156.......789
