How to store this kind of data in an array - c

Question

The input consists of multiple lines.
The first line contains a number n which indicates that the number of rows in the Pascal’s triangle will be n+1.
The second line contains a number m which indicates the number of transactions to be performed on the Pascal’s triangle. Each transaction is given in a separate line. A transaction is a space separated list of integers. The first integer in each list indicates the row number, say R, and the rest of the integers in the list indicate the indices of values in row R. For each transaction, you have to compute the sum of given coefficients in the given row R.
Example: Input will be given in the following format:
5
3
3 1 2
5 1 1 1 4
4 2 3 2
what should be done to store the values of transition lines like
3 1 2
5 1 1 1 4
4 2 3 2
under a single array variable.So that it can be passed to a function completely.

Answer 1

If you make a structure like this you might be able to do what you are trying to do. You can pass structure to function to compute sum of each line.
struct pascaltirangle
{
int size; //The no of lines
int* no_transactions; //To store no of transactions of each line
int** contents; //To store contents of each line. No of contents in line determined by transaction[i]
} dat;
//code to take input of size
dat.no_transactions=(int*)malloc(sizeof(int) * (dat.size+1));
//code to take no of transaction for each line
for(int i=0;i<=dat.size;i++)
contents[i]=malloc(sizeof(int)*dat.no_transaction[i]);
//code to take input for contents[i][j]

Answer 2

It simply adds all the transactions for a line using recursive function.
#include <stdlib.h>
#include <stdio.h>
int add_transaction(int *contents,int size)
{
if(!size)
return 0;
return (*contents + add_transaction(contents+1,size-1));
}
void main()
{
int size; //The no of lines
int* no_transaction; //To store no of transactions of each line
int** contents; //To store contents of each line. No of contents in line determined by transaction[i]
int c1,c2;
printf("Give size of triangle :");
scanf("%d",&size);
no_transaction=(int*)malloc(sizeof(int) * (size+1));
contents=(int**)malloc(sizeof(int)*(size+1));
for(c1=0;c1<=size;c1++)
{
printf("\nGive no of transaction for line no %d :",c1+1);
scanf("%d",no_transaction+c1);
contents[c1]=(int*)malloc(sizeof(int)*no_transaction[c1]);
for(c2=0;c2<no_transaction[c1];c2++)
{
printf("\tFor line %d give transaction no %d :",c1+1,c2+1);
scanf("%d",contents[c1]+c2);
}
}
printf("\nThe sum of the series is :");
for(c1=0;c1<=size;c1++)
{
if(c1)
printf("+ %d ",add_transaction(contents[c1],no_transaction[c1]));
else
printf(" %d",add_transaction(contents[c1],no_transaction[c1]));
}
//Code to free the allocated memory.
}
