Sum of 2 integer numbers in c language.// How to print sum of 2 numbers in c language. Sum of two integer number Sum of 2 integer number: For a sum of 2 integer numbers, we have to take 3 integer variables. 2 for value which we have to add. example: Int a,b; These 2 variable gets value from the user which we have to get addition.  Let's take a=3 and b=2. 1 for an answer where we get the sum of 2 numbers. This variable takes for an answer.  This variable gives us the sum of 2 numbers. For example:  Int sum; Sum=a+b; So sum variable has a value that is an addition of 2 and 3.  And we get answer sum=5. Example:: #include<stdio.h> #include<conio.h> void main() {     int a,b,add;     clrscr();     printf("\nWelcome,CoderFact\n---------------Sum---------------");     printf("\nEnter a First Number :");     scanf("%d",&a);     printf("\nEnter a Second Number :");     scanf("%d",&b); ...
