bracket matching

[Example] The parentheses in arithmetic expressions in C language are only parentheses.Write an algorithm to determine whether the parentheses in an expression are paired correctly. The expression has been stored in the character array exp[], and the number of characters in the expression is n.

int match(char exp[],int n){char stack[maxSize]; //maxSize is a defined constantint top=-1;int i;for(i=0;i<n;++i){if(exp[i]==')')if(top==-1)return 0;else--top;else if(exp[i]=='(')stack[++top]='(';}if(top==-1)return 1;elsereturn 0;}
