Write a program file_max.c that reads a set of integer numbers from a file and prints out the maximum number to standard output. The name of the input file should be specified as a command line argument.
Solution
#include<stdio.h>
int main(int args, char *argv[]){
if (args != 2){
printf(\"invalid execution\");
exit(0);
}
FILE *fp;
char ch;
fp = fopen(argv[1],\"r\");
int max,n;
fscanf(fp,\"%d\",&max);
while((ch = fscanf(fp,\"%d\",&n))!=EOF){
if(n>max)
max = n;
}
printf(\"The max number in the file is : %d\",max);
return 0;
}
--------------------------
execute this with the required file name.
