1 to achieve the reverse order of the input string string output.
2 If a number is exactly equal to the sum of its factors, this number is called a "complete count." For example, 6 = 1+2+3 identify all End counts less than 10,000.
3 The following procedure is the function of a 4 × 4 array rotated 90 degrees counter-clockwise output, requiring random input data in the original array, the new array with 4 rows 4 way output
4 Programming printing Pascal s Triangle.
5 to achieve the output of the input string in reverse order
6. Achieve string copy function strcopy (char* src, char* dest)
7 Find the approximate value of Pi. Can use the formula (eg: pi/2 = 1+1/3+1/3* 2/5+ 1/3* 2/5* 3/7+ 1/3* 2/5* 3/7* 4/9+ .....)
