You may simply map the split, filter if it makes a size 2 tuple, and zip it to get the values separately: In[9]: l=[‘Name’, ‘AMAZON.COM – TOT RETURN IND’, ‘AMAZON.COM INC – NET CASH FLOW – FINANCING’, ‘AMAZON.COM INC – NET CASH FLOW – INVESTING’, ‘AMAZON.COM INC – NET CASH FLOW-OPERATING ACTIVS’, ‘AMAZON.COM INC – … Read more
You could do something like this: string = ” for t in range(1,8): if t % 2 == 0: # if t is even multiply t by 3 and add t to the string string += str(t * 3) + ‘ ‘ else: # if t is odd simply add t to the string string … Read more
You can use char[] to read input. I have modified your program as follows; int main() { int sum=0; int pos=0; int neg=0; double ave=0; char arr[100] = {‘\0’,}; std::cout << “Enter an integer, the input ends if it is 0: ” ; gets(arr); int index = 0; char ch[1]; bool negativeNumber = false; while(true) … Read more
