    Post sorting strings

    Code:
    // string sorting
    
    #include<stdio.h>
    #include<string.h>
    
    int main(){
    
    char name[5][10]={"suresh","chanaka","sarith","Adnan","queen"};
    char temp[10];
    
    int k,i,min;
    
    for(i=0;i<4;i++){
    	min=i;
    
    	for(k=i+1;k<5;k++){
    		if(strcmp(name[k],name[min])<0)
    		min=k;
    	}
    
    	temp=name[i];              // error
    	name[i]=name[min];     // error
    	name[min]=temp;         //error
    
    }
    
    for(i=0;i<5;i++){
    printf("%s\n",name[i]);
    }
    
    return 0;

    You cannot assign into arrays.

    If you want to move strings around, use strcpy.

    Code:
    	temp=name[i];              // error
    	name[i]=name[min];     // error
    	name[min]=temp;         //error
    Code:
    	temp[i]=name[i];            
    	name[i]=name[min];  
    	name[min]=temp[i];

    Code:
                    temp[i]=name[i][k];            
    	name[i][k]=name[min][k];  
    	name[min][k]=temp[i];
    Try this, although 'k" may not be the correct subscript to use.

    The use of strcpy() should work.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    Code:
    strcpy(temp,name[i]);
    	strcpy(name[i],name[min]);
    	strcpy(name[min],temp[0]);
    you meant like this??
