what is Algorithm || how to write Algorithm || Algorithm kaise likhte hai

 Criteria to be followed by an Algorithm The following is the criteria to be followed by an algorithm: 

• Input: There should be zero or more values which are to be supplied. 

• Output: At least one result is to be produced. 

• Definiteness: Each step must be clear and unambiguous.

 • Finiteness: If we trace the steps of an algorithm, then for all cases, the algorithm must terminate after a finite number of steps. 

• Effectiveness: Each step must be sufficiently basic that a person using only paper and pencil can in principle carry it out. In addition, not only each step is definite, it must also be feasible


Example

 Let us try to develop an algorithm to compute and display the sum of two numbers 

1. Start 

2. Read two numbers a and b 

3. Calculate the sum of a and b and store it in sum 

4. Display the value of sum 

5. Stop 


#include<stdio.h>

#include<conio.h>

void main(){
int a,b,sum;
printf("Enter Any Two Number : ");
scanf("%d%d",&a,&b);
sum=a+b;
printf("\n Sum Of Two Number :  %d",sum);
getch();

}

Write and explain the following types of functions with the help of an example program for each (i) Function with no arguments and no return value. (ii) Function with arguments and no return value

hello Write and explain the following types of functions with the help of an example program for each  (i) Function with no arguments and no return value. (ii) Function with arguments and no return value. ANS-    1:  Function with no arguments and no return value: OUTPUT               In this type the function has no arguments, it doesn't receive any data from the calling function. Similarly it doesn't return any value, the calling function doesn't receive any data from called function.  So there's no digital communication between calling function and called function. #include<stdio.h> #include<conio.h> void sum(); void main() {        clrscr();     sum();     getch(); } void sum() {     int a,b;     printf(”Enter any two numbers:”);     scanf("%d%d",&a,&b);     printf(”sum= %d”,a+b); } In this function no return and no argument means create sum function. no any return type, void is no return type data type.  all processing is done inside
