C program prints garbage values - c

Question

My main problem is when i run the program it not work and a runnig time error is jumping on my screen. Can someone explain me whats the problem and help me?
*argv[i] is the adress and ignore the fact i don't have any free for my mallocs.
int main(int argc, char** argv)
{
FILE* file = 0;
file = fopen(argv[1], "r");
int numOfLines = countLines(file), i = 0, ch = 0, j = 0, flag = 0;
char** content;
content = (char**)malloc(numOfLines * sizeof(char*));
int* charsInLine = (int*)malloc(numOfLines * sizeof(int));
countCharsInLine(file, charsInLine);
fseek(file, 0, SEEK_SET);
for (i = 0; i < numOfLines; i++)
{
int lenOfFile = 0;
fseek(file, 0, SEEK_END);
lenOfFile = ftell(file);
content[i] = (char*)malloc(charsInLine[i] * sizeof(char) + 1);
content = fread(content, 1, lenOfFile, file);
}
for (i = 0; i < numOfLines; i++)
{
printf("%d string = %s", i,content[i]);
}
fclose(file);
getchar();
return 0;
}

I am going to assume countLines and countCharsInLine works correctly
Here is the updated code with comments
int main(int argc, char** argv)
{
FILE* file fopen(argv[1], "r");
if (file == NULL) {
// Output some error message
return EXIT_FAILURE;
}
int numOfLines = countLines(file); // I assume this rewinds.
char** content;
content = malloc(numOfLines * sizeof(char*)); // Do not need a cast
int* charsInLine = malloc(numOfLines * sizeof(int));
countCharsInLine(file, charsInLine);
rewind(file); // Easier to read the fseek
for (int i = 0; i < numOfLines; i++)
{
content[i] = malloc(charsInLine[i] + 1); // * sizeof(char) - Do not need this as sizeof(char) is defined as 1
// Reading one item of size charsInLine[i]
if (fread(content[i], charsInLine[i], 1, file) != 1) {
// Some error has occurred
fclose(file);
return EXIT_FAILURE;
}
content[i][charsInLine[i]] = 0; // Add null character
int ch = fgetc(file);
if (ch != '\n' && ch != EOF) { // Should be reading either the new line at the end of the line, or EOF
// Some error has occurred
fclose(file);
return EXIT_FAILURE;
}
}
fclose(file);
// Should free up the stuff that is malloced - I leave that up to you
return EXIT_SUCCESS;
}
