Write a c program to add 2 no without using plus operator?
You can make use of pointers to achieve this.void add( int *a, int *b){(*a) += (*b);}Now if two numbers a and b are given and you need to store the value in variable c, then you would perform:c = a;add(&c,&b);

How do you add matrices?
You add matrices by adding their respective terms - e.g. the element in the first row and sixth column of the sum is the sum of the elements in the addends' first rows and sixth columns. Wikipedia has a nice example of matrix addition that I linked below.
