Obrigo conseguir ;D

Fiz um projeto final de java so que foi em trio. como somos novatos, acaba que um faz uma implementação e o outro não sabe fazer o mesmo. certamente isso aconteceu comigo um dos meus colegas de trabalho fez o banco so que deixo em memoria como troca para o banco de dados do MysQl? private List<Oficina> oficinas;

Escreva uma rotina em C que receba uma matriz de inteiros, X[ ][ ], e dois inteiros n e m que indicam respectivamente o número de linhas e de colunas de X. A rotina deve criar dinamicamente e retornar um vetor que Soma-Colunas, SC[ ] , composto pela soma dos elementos de cada coluna da matriz X. Exemplo para X (3x4): 2 5 1 0 Entra X: 1 2 3 4 10 20 30 40 sai SC: [ 13 27 34 44 ] Fazer um programa para testar a rotina. #include <stdio.h>int main(){ int X[10][10],j,i,n,m,k,SC[1]; srand(time(NULL)); //SC = (int *) malloc(sizeof(int)); printf("\nValor de Linhas:"); scanf("%d",&n); printf("\nValor de Colunas"); scanf("%d",&m);//Matriz em formato matricialprintf("\n :: Matriz NxM entre 0 e 9 ::"); for(i=0;i<n;i++) { printf("\n\n"); for(j=0;j<m;j++) { X[i][j] = (rand()%9 + 1); printf("\t%d",X[i][j]); SC[k]+=X[i][j]; } } printf("\n____________________________________________________________________\n"); //soma coluna for(j=0;j<m;j++)printf("\t%d",SC[k]);printf("\n\nDigite qualquer TECLA para TERMINAR o PROGRAMA .... ");getch(); return 0; } queria ajuda sobre o somatório das colunas. alguem pode ajudar.
