FloydWarshall infinite

Question

iam amateur at programming. I am trying to show each steps of this algorithm but i want to present 1000 as INF on each D matrix.

need more lines to submit need more lines to submit need more lines to submit need more lines to submit need more lines to submit need more lines to submit need more lines to submit need more lines to submit need more lines to submit need more lines to submit need more lines to submit

#include <iostream>
#include <limits>
#define INF 1000

using namespace std;

/* my example matrix is 
0  3  inf  7
8  0   2  inf
5 inf  0   1
2 inf inf  0

i want to write that each D matrix show 1000 as INF

void FloydWarshall(int **dist, int V){

int i,j,k;

    for(j = 0; j < V; j++){
        cout<<dist[i][j]<<"     ";

Answer 1

if (variable >= 1000) { printf("INF"); }

I chose a random variable name, but this logic should do what you want.
