WebC has the following conditional statements: Use if to specify a block of code to be executed, if a specified condition is true. Use else to specify a block of code to be executed, if the same condition is false. Use else if to specify a new condition to test, if the first condition is false. Use switch to specify many alternative blocks of code ... 当r (A) ≠ r [A, b]时，无解（比如 x + 2y = 1, 2x + 4y = 3）；当r (A) = r [A, b] = n 时，有唯一解（比如 2x + 3y = 0, 3x + 5y = 4）；当r (A) = r [A, b] = r < n, 有无穷解 (比如 x + 2y = 3) 对于某些无法使用常规解法的方程，比如 x^ {2}+3x+2 = e^ {x} ，基本都要用到 迭代 的办法，比如二分法，牛顿下山法，弦割法等等，通过一些方法使迭代次数减少，快速收敛可以减少计算量和程序时间， 这里是代码 （代码有点儿烂，仅供参考） 总之，对于1.2两类，通过对方程组整理，转换为矩阵来求解就可以，写代码也是一样的逻辑，对于3类，需要用到诸如二分法的方法来求解。
