根据测试用例扫描多个变量？

Question

I want to calculate sum of arithmetic progression in which we have to take 3 variables from user. a=first number, b= step size/increment, c=length of sequence. If there are more than 1 test case , say three, then I have to scan a,b,c three time. How to do this? Eg scanf (" %d %d %d", a,b,c); 3 times without affect initial values in first test case.

Answer 1

If you know no of test cases read it first and store it in a variable.

int calculate_ap(int a, int b, int c)
{
    //Implement function to calculate Arithmetic progression and return the result
}

int main()
{
    int test_cases = 0;
    int a, b, c;
    scanf("%d", &test_cases); //Reads no of test cases
    while(test_cases--)
   {
        scanf("%d, %d, %d", &a, &b, &c); //read A, B, C
        printf("%d\n", calculate_ap(a, b, c));
   }

}

Hope this helps.

put scanf (" %d %d %d", a,b,c); inside a loop then in the same loop do your coding what you want to do with the values, make sure to write this line scanf (" %d %d %d", a,b,c); before your working code. or if you want to save values then declear array for a,b,c like aValues[] bValues[] cValuesthen[] then put your data inside the array through loop.
