格式化我的输出方程

Question

尝试打印出polynomail即10X^0 + 1 * X^1和9 * X^0 + 1 * X^1然而多项式打印出

10X^0 + 1 * X^1 + 9 * X^0 + 1 * X^1，这里是我的for循环式

for(int i=0; i<=p->deg; i++) { 
    if (p->coeffs[i]==0) 
     break; //dont want to print out any 0 constants 

    cout << p->coeffs[i] <<" * " << x << "^"<<i << " "; 

    if (p->coeffs[i]>0 && p->coeefs[i+1]!=0) 
     cout<< "+"; 

} 

Answer 1

用途：

if (p->coeffs[i]>0 && (i != p->deg)) 
     cout<< "+"; 

而且，你不应该break时p->coeffs[i] == 0，可其他未来系数不为零。

if (p->coeffs[i]==0) 
      continue; //dont want to print out any 0 constants 

而且，所以我认为以下应该工作

for(int i=0; i< p->deg; i++) { //Notice only < sign 
    if (p->coeffs[i]==0) 
     continue; //dont want to print out any 0 constants 

    cout << p->coeffs[i] <<" * " << x << "^"<<i << " "; 

    if (p->coeffs[i+1] > 0) 
     cout<< "+"; 
    }
