Question

11. O/P? point out if there is any mistake in program?

char* fun1(int aNum)

{
int d, end =4;
char decimal[5];
int begin = 0;
decimal[5] = '\0';

while(begin > end)
{
d = aNum % 10;
decimal[begin++] = d + '0';
aNum = aNum / 10;
}
return decimal;
}

int main()
{
int num = 12345;
printf("number %d after fun1() is called is s%", num, fun1(num));
}

Answer 1

Make two changes
1. Make the character array decimal static
2. Change s% to %s in printf function.
