C code for Converting while Loop to for Loop
Posted by Saurabh on April 29th, 2010
Converting a while loop to for loop has always been an area of interest for the programmers. Many times, like while using OpenMp for parallelization of sequential C code, we have to convert all the while loops to for loop. The C code given below operates on the input file test.C and generates another file, for.C [...]
C Program for Matrix Multiplication
Posted by Saurabh on April 21st, 2010
The ordinary matrix multiplication is the most often used and the most important way to multiply matrices. It is defined between two matrices only if the width of the first matrix equals the height of the second matrix. Multiplying an m×n matrix with an n×p matrix results in an m×p matrix.
The C program below show [...]
