打印字符串数组时出现分段错误和代码 139

Question

I get an error 139 and a segmentation fault while trying to run, I'm a little baffled since I'm not accessing or creating any files or even getting input. I'm simply printing three arrays in order.

#include<stdio.h>
int main(){
int i,x;
//set the values of the names
char nmbr[3][8]={
    "Andrés",
    "Manuel",
    "Peter"};
//print characters of the name 1 by 1
for(i=0;i<3;i++){
    while(nmbr[i][x]!='\0'){
        printf("%c",nmbr[i][x]);
        x++;
    }
    putchar('\n');
}
return 0;
}

Answer 1

x is not initialized which is UB

for(i=0;i<3;i++){
    x = 0;
    while(nmbr[i][x]!='\0'){
        printf("%c",nmbr[i][x]);
        x++;
    }
    putchar('\n');
}

Answer 2

x is uninitialized. Your compiler should warn you about this.

You probably want x=0 before the while loop.
