does anybody know where can i find the source code for prim algorithm.or can u help me with the code

i know how floyd's algorithm works

i think they are similar but i dont know how to do itCode:void floyd2(int n, long W[5][5], long D[5][5], long P[5][5]) { int i,j,k; for(i = 1;i <= n;i++) for(j = 1; j <= n;j++) P[i][j] = 0; D = W; for(k = 1;k <= n;k++) for(i = 1;i <=n;i++) for(j = 1;j <= n;j++) if(D[i][k] + D[k][j] < D[i][j]) { P[i][j] = k; D[i][j] = D[i][k] + D[k][j]; } }
